It's chinese and an official publication, if the other makes anything explicit I think they go to jail... from what I heard anyway
The media in China is incredibly censored in relation to anything LGB. The author is likely pushing it by having one character refer to themselves as gay, and showing a bit of a kiss, as well as showing the realities of the homophobia the character faces. Nothing about say any university students self-organising a pride or lgbt rights march which would seem a more normal activity for uni students than a bloody sports day, as this would mean showing a self-organising community and how lgbt rights are officially mistreated.
If after they finally get together it's followed by "the end" I'm going to throw myself from the top most tower!
