Jaehee loves Jeong so much that he stays his friend even after Jeong gets married and has his son, Yoo-ahn. Hearing little Yoo-ahn calling his mom triggers Jaehee's jealousy, and he tells Yoo-ahn to call him ""Mom"" when they're alone. Unfortunately, this becomes a kink that makes it impossible for Jaehee to be around Jeong and his family, and he ghosts them soon after. But when Jaehee runs into Yoo-ahn 14 years later, Yoo-ahn not only remembers Jaehee's shameful kink but also confesses his love for the older man! Could their impulsive night together be the start of a questionable romantic relationship…?
