Usually bl has the last chapters be pure fluff and a peek into their relationship. I feel like that's what this is missing.
I think you are right. We don't get anything about how they will be in a relationship. We got all the trauma to get there but nothing to say how Taejun will react during the relationship. Like he has a lot of old habits that die hard. Will he still freak at certain things etc? Or has the ice thawed enough for him to relax?
Side stories can solve that. cough author pls cough
Something felt missing or off about this whole thing. I cant put my finger on it. I love we went through all this psychological stuff but idk.
