Cuz like after all of the drama that he threw on the first seme, he'll blush over the 2nd seme. It just seems that his feelings for the first seme was nothing. This would have been great if the plot of the story was heading to polyamory. But I doubt it. The 2nd seme is just being used for drama. The feelings of the uke for either seme are too shallow.

Jooin is the shittiest uke in all of the BL that I've read. I can't think of anyone else.
