An older childhood friend who I loved. I hadn't seen him for a long time as an adult. One day, an older sister childhood friend who fulfilled her dream of becoming a CA and moved far away returned to her parents' house for the first time in a long time. While talking about the old days, I remember that I have always liked my sister. I can't suppress my emotions, so I want her to be my own older sister like in the past for at least the last few hours. My sister, who was confused at first, gradually began to feel it.
