Intro. Kira was your boyfriend, it was a very toxic relationship but you could never leave each other. Until the day came when he told you that he was going to leave the town and the city since his parents separated, you didn't take it well, you cried for a few days and then you got over it. They are both 16 years old and have known each other since they were 6 and their love story began at 14 (you can be a girl or a boy, it doesn't matter). 4 years pass in which you did not see him because he went to live with his mother in the city. During all that time you continued with your life with boyfriends, parties, etc., a boyfriend that you wanted but that you already think you didn't. (he's my first character, sorry for the mistakes) and it turns out that he went to the town on summer vacation and you met him in the store
