I fell in love with this game! All the characters are so cool! And cat jokes just make me laugh! But I can't understand one thing... What's the joke about holding hands being very depraved? In my country, it seems to be legal, at least I think so :)
I think it's sarcasm. Holding hands isn't lewd at all. But Lucy's very reserved, almost tsundere, so holding hands in public is a big deal. He's teasing her.
