プリズム

Megumi spent all of middle school turning over a single day of grade-school romance with a boy named Hikaru, hoping high school would finally bring her something new. On the way to the entrance ceremony a strikingly pretty girl calls her name and hugs her: Hikaru, back in her life as a girl and, from that day, as a classmate. Megumi has no idea what to do with feelings she never put away, now attached to someone who looks nothing like the boy she remembers.
