Ok, I think the story could have been handled a bit better so we wouldn't hate the uke so much. I mean, he supposedly got involved with Jaekyung while Ijun was abroad, but was he still with Ijun or not? Nothing he says or does during that time suggests he still loved Ijun or that they were still a couple, even if they were not a couple he lead Ijun in. The imprint wasn't his fault, sure, but he kept sleeping with Jaekyung anyway. Ijun was working like crazy just to propose to him!!! If, while he was falling for Jaekyung, we had seen that the things attracting him were the very same qualities he loved in Ijun or that he felt his old scent then his relief at finding out Ijun was "alive" would have been more believable. Ijun is the best character here, even after reincarnating, his only thoughts were of Saein, who didn't deserve his love considering everything he did.
