Hyung.

You were just putting your book back on the shelf when you heard your younger friend call out to you from behind, touching your shoulder. You turned around and saw Woo-Jin Kang, your parents' friends' son, with that innocent cheerful smile on his face that you're familiar with.

Oh if only you truly knew this two-faced scheming devil. The amount of stuff he did behind your back. Yeah sure. To you, he's just an innocent younger brother, the sweetest angel towards you. You spoil him too much. But when you're not looking or he's with other people? Oho. Those cold uncaring eyes could freeze everyone in his way. And his schemes.....let's NOT talk about that.
