Watching BL shows and dropping BL shows I've figured out what is first and most important thing to me.

The acting and the chemistry between the lead characters.

You can tell in the way they touch each other in scenes and the looks in their eyes. So far, there are only three pairs of actors where I can say with no doubt that they make the love feel real between the characters (see my "good pda" list).

The actors don't have to be perfect, but I need a significant amount of moments where the love feels real. The initial interactions can still be awkward because it makes sense getting familiar with a person. But I want to be able to feel the want from both characters' emotions. I've only completed 10 shows, but everything I've given good rating has the kind of acting and chemistry I'm looking for.

I wanted to like this show. The premise is amazing and the writing is good. The music for the important moments is very moving. The problem is that both the past life couple and the present life couple, the love didn't feel real. It felt like acting. And maybe my criteria is harder to meet than I realize. But more than 50% of the shows I've watched have the acting I'm looking for.

I know this is a highly regarded series, but it misses the most important thing I'm looking for: the comfortability between actors.
