So I have this theory about our Yacchan...

I thought of this at like 1 am and might be tripping here but,, I think Yacchan is pretty much bi or has internalized homophobia. I mean, he did like a girl in the past (but that girl liked Yu), and I think now he likes Toono but doesn't know how to deal with it because he's been pretending to be someone else for so long, and was probably shook when Yu started liking Toono. He seemed rly disgusted when Toono thought he liked Yu, hated the random classmate that confessed to him, and called Tamura a toilet which seems overly hostile all in all. Anywaysss would love to hear your theories because I think it's fun to analyze these characters imo...
