Sweet Girlfriend 3 dropped on September 26, 2025, and I blazed through all five heroine routes plus the bad ending in exactly five days. The biggest selling point? No route locks whatsoever – pick whoever you wanna pursue right from the start, no strings attached. But don't think you can just wing it; the route transitions are pretty sloppy, and one wrong choice will send you straight to the single ending. This guide spells out every key choice's affection changes in plain numbers – just copy my moves and you're golden. I've also bundled my own meticulously translated file pack, so even raw-Japanese-phobic players can safely enjoy. The key thing is, every single route has been personally tested and verified. If the numbers are wrong, come flame me in the comments section.

一、Yumogi Kananno Full Choice Walkthrough

Kananno's route is my top recommendation – the atmosphere is absolutely top-tier, especially the hot springs town scenes. The main draw is how her tilted-head fishing pose absolutely hits the sweet spot; she went straight into my 2025 waifu list after clearing her route. The most stable affection gains – follow my choices and you'll never go off-track.

Starting Moves:

1. Enter your ID and start the game

2. MUST SAVE at the first choice – this is the starting point for all branches

Core Choice Flow:

1. 首を傾げる叶夢ちゃんの釣りを見る (Watch Kananno-chan fishing with her head tilted)

↓ Hiyoriyama Hot Springs Street → Kananno Affection 33% (Scene 1)

2. Mountain Park

↓ Kananno Affection 41% (Scene 2)

3. MUST SAVE again at the second choice – this is where you branch off for bad end or single route

4. Gosho-in Academy ~ Courtyard

↓ Kananno Affection 53% (Scene 3)

↓ Kananno END (Route Complete)

二、Yumogi Shimumu Full Choice Walkthrough

Shimumu's character is pretty interesting – ice cold and sharp-tongued on the surface, but the flirting happens so often you'll question reality itself. I counted – the protagonist gets roasted a total of 22 times, 5 times in the common route and 17 in her personal route. If you're into the whole "tsun but actually dere" vibe, this route absolutely delivers. Her affection values are negative, but smaller negative numbers mean closer relationship, so don't panic.

Route Start:

MUST LOAD from the very first choice – pick wrong and you'll be back in Kananno's route

Core Choice Flow:

1. 興味なさそうな柳木さんの釣りを見る (Watch Yumogi-san's uninterested fishing)

↓ Gosho-in Academy ~ Classroom → Shimumu Affection -200% (Scene 1)

2. Hinashita Shrine

↓ Shimumu Affection -150% (Scene 2)

3. Gosho-in Academy ~ Classroom

↓ Shimumu Affection -120% (Scene 3)

↓ Shimumu END (Route Complete)

三、Kohsaka Sayu Full Choice Walkthrough

Sayu is your standard junior/kouhai character – her cautious, timid appearance makes you want to tease her and protect her at the same time. This route is the shortest and sweetest, without too many twists and turns, perfect for players who want a quick clear. Affection starts at 0 but ramps up at a decent pace.

Core Choice Flow:

1. おっかなびっくりなさゆの釣りを見る (Watch Sayu's nervous, jumpy fishing)

↓ Gosho-in Academy ~ Hallway → Sayu Affection 0% (Scene 1)

2. Rakuroura Dormitory

↓ Sayu Affection 20% (Scene 2)

3. Maruyama Aquarium

↓ Sayu Affection 30% (Scene 3)

↓ Sayu END (Route Complete)

四、Gosho-in Touka Full Choice Walkthrough

Senior Touka is the mature, intellectual type, and that detail about her being concerned with the fishing line's end is especially interesting. Starts with the highest affection – right off the bat at 53%, making it super smooth to clear. The aquarium scene has a nice surprise, so take your time to savor it.

Core Choice Flow:

1. 糸の先が気になる御所院さんの釣りを見る (Watch Gosho-in-san's fishing while concerned about the line's end)

↓ Rakuroura Dormitory → Touka Affection 53% (Scene 1)

2. Hiyoriyama Hot Springs Street

↓ Touka Affection 60% (Scene 2)

3. Maruyama Aquarium

↓ Touka Affection 66% (Scene 3)

↓ Touka END (Route Complete)

五、Ikaruga Lady Full Choice Walkthrough

Lady is the half-senior who stays completely unfazed even while fishing. Slowest affection growth, but the most interesting character setup. Players looking for hard mode should save this route for last – it requires some patience.

Core Choice Flow:

1. 淡々と釣りをする斑鳩先輩の釣りを見る (Watch Lady-senpai calmly fishing)

↓ Maruyama Aquarium → Lady Affection 3% (Scene 1)

2. Rakuroura Dormitory

↓ Lady Affection 5% (Scene 2)

3. Rakuroura Dormitory (yep, same spot)

↓ Lady Affection 8% (Scene 3)

↓ Lady END (Route Complete)

六、Bad End / Single Route Walkthrough

The bad ending isn't just a simple failure – it's a complete single route with full story content. MUST LOAD from the second choice and deliberately avoid picking anyone to trigger it. Don't skip this if you want the full experience.

Core Choice Flow:

1. Gosho-in Academy ~ Classroom

↓ Shimumu Affection -200% (Scene 1)

2. Gosho-in Academy ~ Hallway

↓ Sayu Affection 0% (Scene 1)

↓ (Single Route Complete)

七、Post-Game Review & Evaluation

image.png

Congrats to everyone who finished Sweet Love 3, and thanks for reading my guide. This game is absolutely packed with content – atmosphere, music, character designs, everything feels just right. Ranks in my top 3 moe games of 2025, with top-tier visual quality and voice acting.

The flaws? Mainly the sloppy route transitions between individual storylines, with some paths feeling a bit forced. But the merits far outweigh the drawbacks – the overall experience remains one of the few high-quality moe offerings on the market. Especially that no-route-lock design – it's a godsend for players who only want to pursue specific characters. Just pick who you want and you're done, no need to slog through characters you don't like just to unlock stuff like in some other games.

I've pinned the guide pack and my translation files in the top comment – grab 'em if you need 'em. Got questions? Drop a comment and I'll reply ASAP. At the end of the day, this game tests your time management and patience. Follow the guide and full CG/replay gallery is yours for the taking.
