I'm not talking about someone else. It's this author. They have a Twitter which they rarely update. They drew tons of furries art in it and some NSFW but never upload Papa and Potato pair. And for Weibo, that's more unlikely because they can't post NSFW there. I've been following them for a long time and never see what you're talking about. I look through every post btw
Once they uploaded about this pair on Weibo but it's something wholesome. You can't post anything NSFW on Weibo anyway

So while the series isn't romance, they been drawn together sexually by the author which is why the author makes certain types of panels
