This is so da** stupid. Yejun got a surgery which could have potentially killed him and left his child without their primary parent (when he was afraid what the Choi family would do to him generally) only to get rebonded like 3 months later. They didn't need all this drama. Do-Yoon just had to say he loved him and that would have been cathartic enough for their relationship. This is pis**** me off more than Scentless Trail.
