Yeowool has always known everything about everyone at Hwarang Academy. As Valentine's Day approaches, he's not surprised that Hansung is preparing a confession for Sunwoo. He'd always known that was where Hansung's heart laid. But sometimes even the gossip king can miss things, especially when he's blinded by love.

Every year during the winter season, Hwarang Academy hosts a school wide Secret Santa Gift Exchange. In Banryu's final year, he pulled Kim Sooyeon's name. That year, he got many gifts from someone who knew him very well, but he couldn't figure out who. That year, Banryu realized maybe he was in love. Suryu.
