Li Jia Hang revealed his relationship with Li Sheng on his weibo! What a plot twist, Er Kang ending up loving Xiao Yan Zi!
They look super cute together, and it's super sweet that the NHZGG gang were all congratulating them. Seems like they were dating for a while, because Zhao LiYing mentioned being able to openly talk about this after all these years.

I was seriously fooled by the Zhang Rui/Li Sheng thing for a while, though.
