Nik's manga / #Reencounter(3)

In the middle of chap 10 it was like jiheon had completely changed.The atmosphere also changed it was portrayed like the uke was tsundere,like from pet to lover.If the seme was in love with uke then in the re- encounter why did he behaved like an asshol. I felt a little disappoint since the author like changed the characters thoughts and didn’t showed any developmen.
