Man i love this but it's so full of homophobia, like what's wrong with being gay, like why...

This is in a place that isn't as carefree as most country's like America and most asain countries are really homophobic

I think, homophobia is one of the main theme of the story itself. It's a story about how Yohan, who got estranged from his family because of his sexuality and how it effected him mentally. And how Kangjun choose to hide himself due to the fear of bullying and discrimination bringing out the horrible condition gay people live and their fear, just because of their sexuality.
