I'm fine with them becoming a couple as well (actually, I think I'd prefer them to be a couple rather than the blushing guyXbrown haired guy) but its highly unlikely that the blushing guy will return the black haired guy's feelings(cause hes already in love), and I didn't want to see the black haired guy sad again after all hes been through. Thats why i didn't want the black haired guy to fall in love with him.
I'm hoping that the black hair guy does not fall in love with the brown hair guy(the one who blushes a lot) cause I don't want him to go through even more heartbreak
