You (Amu SUMOTO)

Ryou Sanokawa accidentally runs into Yamada, one of her primary school classmates who bullied her relentlessly and left her with a complex about her breasts. Now in high school, Ryou has the maturity to stand up to her old bully, but what about Yamada? Is he still the bratty kid from all those years ago, or has he too grown up?
