“I hate you!!” Who in this world would know that these three words are used pretty commonly everywhere, especially by these two people who are well known for their “best” relationship in the entire class. Leon, a gloomy guy and Mia, a girl who looks harsh on the outside but actually soft on the inside. Little did they know that both of them are long lost acquaintances, in fact both of them childhood friends. However, it seems only Leon does not have the memory for it and Mia seems to remember it is him during that time but for some reason she does not want to admit it. Therefore, these squabbles tend to happen all the time.  This is the story of how both of the forgotten childhood friends develop from strangers into friends and probably into a relationship?
