I love J-drama: best at showing how family should be, but to know how a messed-up family looks like, we need a work like the Korean movie, "House of Hummingbird"!

Eun Hee's family might seem fine: hard-working parents, caring for their kids' future; but looking more closely and you see a messed-up family: The foundation-father-mother relationship-is deeply damaged, hence other problems like emotional neglect, even physical abuse come; A Cold Family, Indeed!
Expectedly, for Eun Hee, finding warmness outside is the main issue, but unlike many kids in her situation, she is not hopeless, entering abusive relationships. On the contrary, there is something beautiful, something powerful in her which attract people. But from where she got this? The answer should come from her older sister, Soo Hee: Despite the fact that she has her own problems and can't support Eun Hee as one wishes, there is something warm flowing between them. In truth, 'Family' only begins with strong sisterly bond between the two. And it's not just this: The sister with her nice boyfriend provides a good relationship model, showing Eun Hee what exactly she should look for.
The rest is Eun Hee's constant attempts to find warmness outside her home: with her good buddy, with her not great-not terrible boyfriend, with the girl who falls in love with Eun Hee, and surely, with her Chinese teacher who acts as a mother-friend.
Sometimes Eun Hee fails, sometimes she succeeds, but in all these, you can see that she is taking strong steps toward a brighter future, so it's impossible to not be an optimist!
