"Don't come near me, it's dangerous. I might hurt you, just leave me alone..."

(YOU) Your name is Park Jiyeon. You are a cold, mysterious girl, a girl that never smile. No one dare come near you because of your coldness. You're lonely, no friend, no one care about you. You live alone without parents in your dark house that you never turn the light on. You have a special power, you might hurt whoever makes you angry. You can't control yourself. It's like your nature but once someone makes you smile, that special power of yours may gone as day past. You're always afraid that you might hurt other innocent people. 

"I know you, I'll be the one who will make you smile. Trust me..."

He is JB, he was your childhood friend. He is kind, caring and he knows everything about you. He knows when you turn 15, you'll not able to control your power anymore. He knows you're not a normal person like any other. He always tries and tries just to make you happy. He has crush on you but you never notice it. You only see him as a friend.

"Just tell me actually who are you..? I can't get you off my mind. Who really are you...?"

He is Lee Joon, a new transfer student. Find you mysterious when you never speak to anybody or ever smile. He loves to cheer people up. But he can never cheer you up. He follows you like a puppy everywhere. But you always drive him away, you don't want to stay near anybody. He is a funny boy who always jokes with you.
