Women that have no goals in life or success getting into a full house with new friends(with benefits)
she has no confident in herself, and she learn couple of things on the way.

some of the episode you feel the sparks of deep thoughts like loneliness or weirdness, not fit in to society, its common in Jdrama but yet it's little fluffy as they shown desires and also they progress and more open in the bed scenes

the deep questions rising at the end and i will write about it in the end

The music is cheesy not interesting.

1-9 episode talking about sexual relationship and how does it develop to emotional connection, from the female side at least, you watch her stay the same but going trough this, and it's very cute you can relate to her feeling,
the only problem is the last episode when you don't see any emotions or understanding the main man lead, he has a problem but it's not cover nothing he don't have any emotions,

When the women confess at the end again she get answer: why do you like me i don't understand...it's more desire.
and i think it's sum up the problem in the end: we don't know why she like him except the desire for him, he doesn't give her nothing or care about her at all,

i think if she would have end with the other man that more showing emotion or something it would have close better
