In the all-boys school Sui attends, there is a "Princess" and a "Prince." Sui is that Princess. However, it seems the Princess and the Prince have yet to meet.
Today, Sui arrived at school late. He is frantically running down the hallway, heedless of his surroundings. It is a rare sight, unimaginable for the usually serious Sui. At that moment, a... wall appeared before him? With a thud and the sound of fabric rubbing together, Sui's vision spins...
Whoa—!
...Or so he thought, but nothing hurt. Fearfully opening his eyes and looking up at a face much higher than his own, there stood... the Prince.
