Last chapter He Tian helping Lil Mo to pee. So after the peeing chapter there should have been a chapter in which the characters are having the He Tian is leaving conversation to make everything flow. But it went from He Tian helping Lil Mo to pee to everyone is sad without any explanation as to why they are sad.
People are saying He Tian told Mo he was leaving because of past chapters but Those chapters are in the past so they do not flow with the current chapters. People are interpreting it that way because the story never explains why they are sad.
