Sheesh, calm down, sis. His behavior just seemed very confusing to me. He himself said that he doesn't feel like he belongs in the house, and I just had the impression that his whole "crush" on Kazuto was merely for selfish reasons, to prove to himself that he can voice his emotions. How he wrapped all of it up in one single monologue just didn't feel genuine to me, is all.
And if having an opinion is having a hate boner, so be it. You're obviously so thirsty, you do the thinking through your boner.
