Sei (32) brings home a fellow rider after they had fallen asleep standing, leaning against his chest. Turns out, they were a student name Ryou (20), overworked by school, parttime tutoring, and helping his single mother with his two younger brothers. When Sei ate Ryou's uneaten lunch, Sei offered him to work parttime for him, with the same wage as Ryou's tutoring. Albeit rejected, they were surprisingly living in the same building which opened up the opportunity for Ryou to accept. After a month of Ryou's weekly cooking job, Sei began having romantic interest on Ryou. With a surprise peck on Ryou's cheek, Sei realizes that it's a normal greeting among Ryou's family to hug and kiss to show affection. Since then, he sneaks a peck on Ryou's cheek when he goes back home as a brotherly action. Nonetheless, an opportune sleep over and conversation about Sei's singlehood triggered Sei's self-control. Instead of a peck, he kisses Ryou on the lips. Without waiting for a response, Sei advices him to leave if he wanted to even if it also meant quitting his parttime job for him.
However, Sei wakes up to Ryou's cooking and he takes it as Ryou's response. Nonetheless, things weren't too clear and they separated in an ambiguous atmosphere. When Ryou tells Sei he couldn't come, Sei took it that he was rejected. Work occupied him and he didnt need to go home, but when he did, he was surprised with an honest yet ill Ryou.
In an attempt to be a good adult to match Ryou's mindset regarding their age gap, Sei postpones their relationship into kisses just until Ryou graduates in his last year as a high school student.
