During their school days, Jae-woo and Hyun-min shared a unique connection that made them feel exceptional—more than anyone else around them. When Hyun-min receives a significant present from Jae-woo, he believes it signifies a mutual understanding.

Could you let me stay just one night?"* Seriously… how can someone be this brazen?
