that's probably because this isn't a BL manga considering it's serialized in tonari no young jump, it just happens to have a gay protagonist. if the original magazine itself doesn't label it boy's love most likely it won't focus on romance?
Oh wow.. that’s some plot twist I never expected. Wish he didn’t fall for that guy though, age difference wise. But well , you do you buddy. The story is interesting enough for me to not mind of it
