Very underwhelming, I expected too much out of it and it turned out to be a complete lame story!
The story is supposed to be mature but I have found zero relatable points to real life, more like teenagers cosplaying as adults and concerned about sex only!

As for the characters, I disliked how they lacked consistency, characters would suddenly pop out a trait that didn't exist in them initially without any reasonable development turned me off a couple of time, and especially the heroine where every logic and consistency were dropped while shaping her!
DEAR GOD! Fu was so annoying and childish it made it difficult to watch the drama, every scene of her felt like an extended slow and silent movie with the boredom and annoyance that comes with it! Enjouji also lacked logic in her story, while I like her story the most, some of her actions were as annoying as Fuu.

The whole drama is written poorly, the ideas, scenes, touching moments are all scattered around that it doesn't make any sense at all, I hoped it would get better towards the end but it was bitter that I dropped it!!
