I know it honestly sucks but I truly think that he will pose absolutely no issue to their relationship in the long run. I think that he was added so Dr. Kang can finally realize that he’s not ok with losing yiyoung like he thinks he is. In the recent raw yiyoung got a call from Doyeon saying he needed help so he went to go pick him up and he told Director Kang and he was like “what kind of bullshit did I say” after having flashbacks of him telling yiyoung if he leaves he won’t hold him back and it looks like he’s gonna go to the bar himself and get him worried that yiyoung will have a change of heart
why did the author even add a second lead??? Like why??? I dont understand they could have made this story without him, like just a continuation of their couple life and stuff
