The best part was the ending. Because then I could be sure that I would not be tortured further.
Bad dramas bore me. Very bad dramas stress me out.
They should have changed the title to: The Endless Whining of a Bad Story.

The idea is not bad at all. But not well implemented.
The actors were in a race, who is worse?
Dear reader, you don't like what I write? Well, just invent a reason why they couldn't play well. The spaghetti monster drank all the drinks from the actors and so the mood was at its lowest point.
Or you had tickets to a movie theater, bought popcorn, a drink and you wait for the movie, but it just got eaten by Godzilla. Something like that puts the actors in a bad mood, and they really let that show in the movie.

Or you can stick to the truth. Sorry guys. If you don't like your acting partner and can't act that even, then you shouldn't be doing BL dramas. I am appalled and will not change my mind until you do the following:
Stand naked on a bridge at night and stick your left little toe in your right nostril. You sing a song of your choice. You film it and send me the result. Then I'll rate it as a spin-off and take it into account in this rating.

But until then, here's my clear recommendation:
Recommend this drama to those you hate with a passion.
For the rest of you, watch the next Drama!
