If you happen to stumble across this on show with English Subs, here is what you need to know:

A good show, really well executed, awesome acting. 18 Full Episodes and none are boring.
Life lessons learned the hard way, some violence, love that can go wrong, family drama.

A domineering mother who listens to no one and is actually a very evil person. (I really wanted her to die)
A girlfriend who wants what she can't have and will do anything to get it.
A desperate gay friend who is in love with the nicest guy.
A weak, cannot stand up for himself (the nicest guy) who has his life ruined because he could not make good decisions.

Put it all together and what you have is a good, but messy story.

Had the ending been different, I would have rated this show a 10

Now For The Spoiler Hints:
Do NOT watch this series if you are looking for sensual scenes, despite the story line there are none, just some light kissing
Do NOT watch this series if you want a happy ending. Episode 17 is really sad and episode 18 is just stupid (in my opinion)
