Firstly I have to write I didn't read the manga.
When I first saw the title and description of this drama I just though this would be probably some stupid show with really strange plot and cringy acting.
I was totally wrong! The topic of keeping a human pet is really interesting one and it serves as a cause of several really funny situations - I laughed a lot watching this drama which doesn't happen very often. Also there were some situations where I felt bad, sad or angry and I love when some show makes me feel all these emotions. And I have to say until last 2 episodes I really couldn't imagine how this could end for everyone involved and I was surprised how all the personal stories were finished and in the end it gave me the best ending I could wish for.
The cast is very well chosen and I love acting of all the main cast, I really felt for the characters like they were my own friends and in the end I have to admit I cried a lot.
I don't see any negatives on this show, just go and give it a try, you won't regret! Especially if you like some cuddling moments and feelings of unconditional love.
