There are only a couple of things you need to know.

1. This is not a BL (not really at least)
2. You will laugh a lot if you watch it
3. The last two episodes are incredibly moving, I cried and I don't cry easily
4. It is a brilliantly written, acted, produced drama, the cast is brilliant across the board

5. Just watch it and form your own opinion.

If you watch it you will be treated to a thought provoking story with incredibly likeable main cast members, they all get their moments to shine, a great storyline, that never feels rushed yet also never gets boring or bogged down and you will laugh and you will cry. Is there anything more you can ask of any drama?
