Playing visual novels is all about avoiding the wrong choices that lock you into unintended routes, especially in multi-heroine cohabitation stories where one misstep sends you straight to the solo ending or forces you down a character path you never wanted. Roommates, Romance, and Ringing Hearts doesn't bury its options too deep, but the affection system is razor-sensitive—missing one or two critical choices completely alters your ending trajectory. This guide maps out every key decision with clear affection value changes marked. Follow these selections exactly, and you'll lock into your target heroine's route without fail.
