Seong Ha Rin and Park Chanyeol are both high school students living their everyday life. Having been together since birth, there was not a day they did not see each other and experienced the same things. That is until Chanyeol starts his trainee life and tries to balance both friendship and training. The same personality, the same background and hardships - the same feelings?

Chronologically the first story of the EXO series. This story is the prehistory of all the other EXO stories in the series, basically the beginning of everything, but they can be read separately. My stories are written as closely to reality as possible based on real events.

Important note: This story is still in the process of editing!
