Senior year can be a hard year, usually it is, but what's up when you discovers you are the element? How hard can senior year be when you discovers you are the one who have all the forces, you are the only one who can end with Akan, the evil that stalks the world? 

Have a person can change in less than a month? I mean, we were best friends for life and after three weeks he stopped talking to me. I can't find the reason why he did, I really didn't do anything wrong.

Everything started when he began to hang out with that bunch of idiots, which is funny because we have always laughed about Kim Joon Myeon and his stupid friends who always walked as they were special, superior than the rest...and now he was one of them. I don't know why Chan Yeol began to be so idiot, he used to be such a nice boy, he was very funny and charming, he could make you feel the happiest girl in the world even if you were the saddest in that moment. But the previous weeks of his 19th birthday he began to sit with Joon Myeon and others at lunchtime and there wasn't any Fridays for the two of us anymore because he has "things to do with his mates" I just want to punch Joon Myeon in his pretty face, his stupid face, for stealing my best friend. 

And to top it off I'm feeling lately that I will go crazy, I feel that someone is chasing me when I come home and I feel like somebody watches over me all the time ... plus how clumsy I was, I've broken three taps in my house, well it is not my fault, the water pressure was too much...

But I just want that Chan Yeol comes back to be my friend...that stupid of Joon Myeon and his stupid friends stole him from me...

At least I have Lee Bo Na, my best friend, she is always taking care of me, in everything. She is just the best
