(Y/N) and Oikawa were in a perfect relationship, well at least that was the case. 5 years ago Oikawa had walked out on (Y/N) to play national volleyball however, the volleyball nationals had come to an end for the year, and Oikawa and his team had finished touring. In addition, Oikawa decided to come home, but to his surprise he runs into (Y/N), and discovers somthing that gilts him into wishing he had stayed.
