Lee Donghae, was my school teacher before he married to my step brother Lee Hyukjae, you can say I accidentally introduced them and made them closer, whenever I got into trouble back in the school. Long short story, after they knew each other, they became the couple and then got married few years later.

I was drunkard and living a helluva miserably life before I manage to settle my heart-broken feeling. Why? Because I’m also in love with my ex-teacher Lee Donghae, but I was too young and he is my teacher, also he’s in love with my step brother Hyukjae and they got married as well.

So, tell me! What can I do as an outsider to the two love-birds?

Other than keep this unrequited love deep down inside of me.

Yep! I know miserable life.

Sadly,

Two years after they got married, my brother died in car crash and left Donghae alone with me. We’re living in the same roof, you see, the three of us, before Hyukjae hyung passed away and now, there are only the two of us left.

Lee Donghae and I, Cho Kyuhyun.
