The Love Interest guy is simply an empty shell with no soul inside. The actor of that Love Interest is so so so bad.

The Protagonist is amazing. I really saw emotions and reactions within him. However, this brought contrast of acting between the two leads to an even more obvious point. It presented how realistic and genuine Protagonist seems and how empty and emotionless the Love Interest seems.

Also, I think the problem is also that Love Interest has bad lines and zero personality, so he can't express himself fully, or at all.

In any case, I've watched a few amazing BL dramas recently and I have no patience for this low-quality production of cheap emotion and bad acting.

I think my main problem is really in the way the Love Interest is portrayed. I'd honestly just want to stay for Team and Win...
