All Characters Affection Points Fast-Grinding Guide
Don't be stupid and waste time spamming gifts daily for affection points. The core rule is: Do daily fixed events, choose the right keywords in conversations.
Misaki likes talking about bookstores and coffee, Natsuki eats up sports compliments, Aoi requires directness and boldness, Akemi needs to be praised for her body management, and Sayaka wants literary discussions—not sleazy talk. Talk to them first every day, then do their corresponding side quests, and affection will skyrocket.
Here's the key: Days 15-20 are the golden period—don't waste time diving or fishing. Focus entirely on grinding characters. Find them at the water bar during business hours at night, one chat can boost 15-20 points. Remember to save—if you pick the wrong option, just reload.
Misaki Route Story Choice Branch Guide
Misaki's route most easily gets stuck on Day 8 and Day 22. Both days have bookstore-related choices—pick wrong and you're locked into the normal ending.
On Day 8 afternoon, she asks what you've been reading lately. Never say you've been too busy—choose recommend the poetry collection from her store. On Day 22 night, when she talks about her dreams, say you support her opening a bookstore chain—don't mention playing it safe.
One more detail: On Day 14 work option, choose to help her organize bookshelves for an instant 30-point affection boost—other options only give 10. This gap can't be made up later.
Natsuki Route Key Decision Points Summary
Natsuki is a tough girl with a soft spot—never argue with her throughout. Key nodes are only three:
1. Day 6 beach run—she falls. Must choose to help her up and rest with her. Choosing to keep running is instant game over.
2. Day 18 motorcycle race—she asks if you dare ride her passenger seat. Don't chicken out, say yes. If you chicken out here, all future storylines are locked.
3. Day 25 when she mentions family matters, listen seriously—don't brush it off. Get this right and you're halfway to the true ending.
Aoi Route True Ending Unlock Method
Aoi's route is the most hidden—many people don't even know this character exists in their first playthrough. Unlock condition: On Day 5 night at the water bar, she'll be drinking in the corner—initiate conversation. Note: Must visit the water bar at least 8 times within the first 10 days, or she'll leave Nanbin Port on Day 12.
True ending requires three hard conditions: max affection, viewed all her personal events, and on Day 28 choose to find her at the dock instead of attending Natsuki's race. Missing even one locks you into the normal ending.
Aoi's personal events only trigger at night—you can't find her during the day. After 7 PM, check the water bar or dock. There are 6 total events—miss one and you're screwed.
Akemi Fitness Trainer Event Trigger Conditions
Akemi's event triggers depend on time. She only appears at the gym on weekdays from 3-5 PM—you won't find her even if you search the heavens other times.
First trigger: Day 4 afternoon at the gym—she'll actively teach you equipment. Second: Day 11, requires physical stat over 60 to trigger her body measurement assistance. If your stat isn't enough, go running—don't be lazy.
Third: Day 20, now you need to take her out for a diet meal—picking the right restaurant is crucial. Choose a seafood restaurant, not a BBQ stall, or she'll think you don't understand her.
Sayaka Bookstore Hidden Story Unlock
Sayaka's bookstore storyline directly ties to how many books you've purchased. You must buy 20 books total to trigger the hidden story—don't be stingy.
Key moment: Day 16, she'll ask your opinion on modern literature. Must choose critique commercialization, support pure literature. Choose wrong and no amount of book buying helps.
Day 24 she'll invite you to a reading salon—you must go. During the salon there's a question about what you're reading lately—say you're reading her recommendation and affection explodes.
Aunt Exploitation Plot Quick-Skip Technique
The aunt's storyline is long and tedious—many want to skip it. There's a way, but it costs you. Skip working at the water bar for three consecutive days and she'll fire you automatically. But this locks both Sayaka and Aoi routes completely.
The compromise: Work normally Days 1-7, then from Day 8 just click the dialogue daily and leave without completing all tasks. This gets through the storyline in minimal time without affecting other character routes.
There's also a dirty trick: Save your game, then directly change system time to Day 30, reload—entire aunt plot is skipped. But this may trigger bugs—use with caution.
Water Bar Money-Making & Layout Tips
Don't randomly arrange water bar management—layout matters. Put fridge and counter together to reduce walking time. Place tables and chairs by windows for fast customer satisfaction. Don't buy advanced coffee machines before Day 10—waste of money.
The fastest money-making method is selling specials. Don't trial-and-error special recipes yourself—just ask Misaki directly, she'll give you three recipes. Rotating these three yields triple profit of regular coffee.
Don't overstock daily—50 ingredients is enough. Too much wastes money, too little means lost sales. 4 PM is peak hour—save materials for this time slot.
All Endings + Hidden CG Unlock Conditions
Total endings: 12—5 true, 5 normal, 2 bad. Hidden CGs: 8 with various unlock conditions.
True ending requirements: 100% character affection, viewed all personal events, correct Day 28 choice. Missing any locks you into normal ending. Bad ending is simple—flirt with 3+ characters after Day 25 triggers it instantly.
Hidden CG unlocks: Misaki's auto-unlocks after 3rd bookstore event, Natsuki's requires winning motorcycle championship, Aoi's at dock night 5th event, Akemi's after gym body measurement, Sayaka's requires reading 30 books.
Nanbin Port Full Map Exploration & Collection Guide
Nanbin Port's map isn't small—collectibles are scattered.建议分三天探索完，别一天瞎跑浪费时间。
Day 1: Beach area. Find shells in morning, drift bottles in afternoon, campfire traces at night. 15 total collection points—motorcycle is fastest.
Day 2: City area. Rotate between bookstore, gym, water bar, dock. Bookstore has old bookmarks, gym has lost wrist guards, water bar has special cups, dock has ferry tickets.
Day 3: Mountain area. This zone is the worst—collectibles hide in grass. After entering village turn right first—there's an old house with old photos inside. Then turn left—there's a windmill on the mountain peak with a treasure box underneath.
Fishing Spot Locations & Rare Fish Complete Guide
Don't fish randomly—spot and timing are everything. Rare fish only appear in specific weather and time slots.
1. Dock East Side: 6-8 AM, rainy weather, can catch Golden Tuna. Each sells for 5000—get rich on this.
2. Beach Reef: 4-6 PM, sunny, can catch Rainbow Salmon. Required for special coffee.
3. Deep Dive Zone: 12-2 PM, must dive down to fish, has Devilfish. Catching this auto-boosts Aoi route progress by 10%.
Other regular fishing spots are optional—but memorize these three or you'll be waiting another day.
Diving Treasures & Hidden Event Triggers
Diving system unlocks Day 9—don't rush into water, buy intermediate equipment first. Basic gear doesn't dive deep enough for treasures.
Treasure location: Underwater shipwreck, over 30m deep. Contains gold bars and ancient coins—sell for a month's expenses.
Hidden event trigger: After 5 consecutive dives, the 6th triggers Aoi's rescue scene. This event is mandatory for Aoi's true ending—miss it and you're locked out.
Watch oxygen levels—don't be greedy. When oxygen drops below 20%, surface immediately or it's instant game over with no save point.
Motorcycle Rental & All Race Track Locations
Motorcycle unlocks Day 12, rental cost 500/day. Don't be stingy—must rent or you can't do Natsuki route or beach collections.
Total tracks: 5—Beach Straight, City Loop, Mountain Curve, Dock Freight, Night Highway. Each has treasure boxes that auto-collect when riding past.
Race is on Day 25—familiarize all five tracks before then. Familiarization standard: Complete 3 laps without hitting obstacles. Win the race, unlock Natsuki's true ending.
Mysterious Legend Questline Complete Walkthrough
This questline is extremely hidden—many complete the game without knowing. Trigger condition: Day 15 night at bookstore, Sayaka gives you an old book with a treasure map inside.
4-step process: Step 1, find stone tablet at beach per map. Step 2, tablet has password—it's the bookstore opening date, ask Misaki. Step 3, input password to open tablet, get key. Step 4, key opens dock warehouse door for final treasure.
Treasure: 8 hidden CGs, unlocks true ending epilogue when all collected. Not seeing this storyline means you played for nothing.
Save File Location & Backup Methods
Save location: C:/Users/[Your Username]/AppData/Local/SummerBeach/SaveData. This folder is hidden by default—must check "Show hidden files" in folder options.
Backup method: Directly copy SaveData folder to desktop, backup daily after playing. Don't be lazy—this game has high save corruption probability.
Manual save replacement: Copy backup SaveData folder back, overwrite original files. Remember to backup current save before overwriting, just in case.
Save File Corruption/Loss Repair Methods
Don't panic when saves corrupt—there's rescue. First check backups, if none then use Steam cloud.
1. Check game root directory for auto-backup files—files with .bak extension. Change .bak to .dat and put back in SaveData folder.
2. Steam cloud: Right-click game properties, find cloud save option, click restore. Usually recovers to previous day state.
3. If none work, find others' saves online. But this erases all your progress—this is the last resort.
Steam Cloud Save Sync Failure Solutions
Cloud save failure is usually network issues or local file conflicts. Fix steps:
Step 1, close game. Step 2, find local save folder per above, delete all files inside. Step 3, restart game, choose download save from cloud.
If still failing, clear download cache in Steam settings. This trick works 100%. After clearing cache, restart Steam and sync will work.
Launch Crashing/Black Screen Solutions
90% of launch issues are GPU drivers or resolution. First update GPU drivers and restart computer.
If still crashing, find config file in game installation directory, open with notepad, change resolution to your desktop resolution. This game defaults to 1920x1080—unsupported monitors cause black screen.
Ultimate fix: Right-click game exe, properties, check "Run as administrator". If still no good, only reinstall remains.
Low FPS & Stutter Optimization Settings
Low FPS isn't hardware—it's settings. In-game settings, first drop shadow quality to lowest—shadows are the biggest performance hog.
Then turn off water reflection—beach reflections are especially laggy. Also disable V-sync—this game runs worse locked at 60 FPS.
Final step: In GPU control panel, set game exe to high-performance mode. After these tweaks, even a GTX 1060 can hold stable 60 FPS.
