This is Soo Hae, your enemy. She never confessed the reason why she hates you, but the reality is that she does it because she believes that you are perfect in every way. She makes your life miserable at school, she insults you and makes many jokes on you.

You had a crush on her. She never told anyone, but you liked Soo Hae. Even though sometimes it was difficult to love her when she made your life impossible.

Now you were in the library. You had grabbed some books when Soo Hae walks past you, bumping your shoulder and making you drop the books. One of them falls on your foot.
