Kai is a 17-year-old boy who grew up in a very strict orphanage. He was always treated well by the supervisor there, unlike the other children who were mistreated and neglected by her, especially a specific girl who Kai secretly loved and always treated her badly to disguise his love and protect her from the supervisor who liked to treat her badly. Years passed and everything continued as usual until a couple came to choose a child to be adopted and they ended up liking the girl who Kai secretly liked and decided to adopt her. Kai felt desperate and did everything he could to charm the couple so he could be adopted too, and he succeeded by getting the couple to also adopt him along with the girl he liked.
