Between love and friendship. You've been together for 15 years. Which will you choose?
About
Guest and Siwoo have been together since they were children. Studying, playing, through hard times, sad times, and happy times— They were always together. They went to the same middle school and high school, and eventually, they were both accepted into the same university. They were inseparable childhood friends who relied on each other deeply. They thought this friendship would last forever. Until that day arrived. On the day of the university freshman orientation, Siwoo fell in love with Seorin the moment he saw her. But what he didn't know was that Seorin fell in love with Guest at first sight, and that a crack was beginning to form in this long-standing friendship.
