Thank you for playing, I'm glad you liked it 🥰
Sorry to disappoint but this IS how Mairō feels about Mahiro. Sure, it's not that he actively hates him because he doesn't really know him. He does everything he can to avoid Mahiro but it's not out of spite; it's because just looking at him is painful for him. Because it reminds him of everything he couldn't have.
And so, I can't imagine a situation where Kyū, being his only ally, the only person who really understands what he's going through, would be so cruel to scold him or push him to have a relationship with Mahiro. He'd try to do it in very small steps. But anything more than that would feel like a betrayal and complete disregard for Mairō's feelings.
So it is a tight spot to be in, but I think that makes for an interesting dynamic. ^^
