Seulgi and Joohyun were a couple loved by both of their families. But when life became busy for the both of them, not to mention the long distance relationship they had to endure ever since Seulgi started her F1 career, they had no other choice but to go their separate ways. 

Winter break has come and another season of Formula One has finished. It was time for Seulgi to come home after two years, right on time to be present on Jaehyun's birthday. Everything was going well until Joohyun arrived and the two ex lovers meet again after a long time of not seeing each other.
