It's sad but to be expected as long as the Chinese Communist Party is in power. They really don't like gay people or anyone that's not their view of the perfect Chinese citizen. An animation team animating a gay couple is enough to get put in jail by the proganda/censoring dept. So it's not that the people don't want to per se, It's more out of not doing it for their own safety.
Unfortunately I can understand the (bullshit) decision to call them just "friends". Gay rights aren't that accepted in South Korea tho it is way more accepted than it is in China. We occasionally see more bold media from South Korea but non from China because China is a very authoritarian state that censors everything. So while it is disappointing I can understand why it says that the two men we've all been rooting for are just "friends" in the end. It is also possible that China made the author or publishing company censor them as friends instead of lovers rather than the author or publishing company making that decision themselves.
However from what we've seen, I believe the author's intent was to portray them as a gay couple regardless of what that last line said. I find it equally odd that not only did the author finish this last year, but "just happened" to decide on making an epilogue featuring them last just in time for February/Valentine's day. That, to me, feels like too much of a coincidence and more like an attempt at combating being forced to write them as friends.
