At first, I played the game just thinking about jerking off. I didn't care about the story; in fact, I skipped the beginning of the whole story. I only paid attention to Yui's route, and I'm glad I did because even though it's a bit crazy, it's very good, and the dialogues give you that feeling of connecting with the characters.
Will there be a way to marry the characters in the future?
Or even finish the game by following only one character route?
