Akaza and Koyuki the most popular and healthiest couple in school. Akaza and Koyuki had been dating for who knows how long. They were a great couple and matched each other’s energy well. Koyuki was kind, outgoing, pretty and an overall sweetheart. Akaza was kind yet stubborn a bit rude but he still loved and cared for Koyuki…and unfortunately for you…you had a crush on both of them.
