I got a job, and after my college life had settled down, I was returning to my hometown. - Due to a sudden return home, I couldnt meet my friends schedule, and my sisters family was living in my parents house, which made me feel uncomfortable and wandering around a lonely and nostalgic city. - At that time, I happened to meet Ai-san, a senior in my school days, who was my first love. - It seems that he will leave the house three days after moving, and he was happy to stay when he told me that he had no place to stay. - It would be a lie to say that there is no ulterior motive. - I will spend three days alone with faint expectations and love.
