Actually so glad you did your ask because here are my qualms about the series.

One, Doyoon Ye's family is Doyoon Kim's now, whether he likes it or not. Two, ML is a little too down bad (he's willing to KILL for Doyoon??). Three, he just readily believes himself and Doyoon that he's reincarnated?? That's awkward.. like yes, Doyoon is being honest, but no normal person would believe in the supernatural only when it applies to the love of their life. Just was awkward to me.
