The story lacks many things to be honest.
I only give this serie 5 because of the following reasons:
1.Diew was a very dumb character.I think they tried to make him funny but they just couldn't.
2.This is not a BL serie.Actually I don't even know what to call it.
3.This serie lacks character development.
4.No kiss,Not a single moment of affection to please users.
5.The story doesn't even have any strong base.

Plus points
1.This serie has a lot of famous couples that appear as guests.
2.Childhood trauma was explained.

What A BL should be consist of
1.A great story
2.Good chemistry between leads
3.Good acting
4.A little fast romance
5.At least the leads should be kissing if they aren't ending up as a couple.
6.At least ending should make sense.
