Agree. but the plot already feels like it's going in that direction. Disappointingly. Which is both gay identity erasure and also sets up a problematic narrative for bi people in the LGBT community, with the false narrative that they're all cheaters when that's not true at all.
I'm pretty someone mentioned this before to a comment similar to yours. The whole entire story is alluded to Freddie Mercury's life. Supposedly he married his wife despite being a homosexual because he had a different kind of "like". Because of his reputation he hid his homosexual life because he was afraid of being attacked for having the "gay illness". But in the end he died of aids and was HIV-positive.
This essentially what the character is going through. He loves miura but not in the way lovers do. And he feels the need to hide himself constantly from everyone because he's scared. But like Mercury he's finding comfort in those around him that are supportive (to Mercury it was Mary Austin)
I just hope they end as friends. I dont like the trope of falling in love with a girl while he still thinks so bad about himself.
He should learn how to accept his sexuality and love himself as a person, not just "oh, his problems are no more, he found a girl, so no need to think about being gay anymore". It's cruel, like gays and lesbian they just need to fInd the right person of the opposite sex bullshit. Yeah, bisexuality exist, but in this manga I feel it'll be used to erase the protagonist problems and not really a way to represent bisexuals.
