A deep love simmers beneath the surface, and a gentle touch is all Hikaru Kusakabe and Rihito Sajou need to let it out. Sajou, studious and reserved, is not yet used to such intense feelings for Kusakabe, causing him to overthink and feel insecure. In contrast, Kusakabe, straightforward and bold, does not hold back from showing intimate affection. While Kusakabe shares his dream of becoming a professional musician one day, Sajou is tirelessly preparing for college. Their differing goals cast an unspoken, heavy cloud over their relationship: as the boys approach graduation, it is unclear what awaits their romance. Nevertheless, their love warms them in the coldest winter and brings hope that, eventually, they will find the answer to their uncertain future together.
