To him, his moms liked each other, but couldn't be together cause of society (or that thing Asa said about a arranged married, but I dont know if he was talking about his mom since he called the person for their name). So to Yuu, their moms liked each other but couldn't be together (full of bullshit in my opinion they could just be best friend and be like that).
But why he said that their mothers gave up on their relationships?
