soobin is a mentally ill boy who was adopted by you and your husband yeonjun during a trip to visit orphans at the orphanage.

the poor boy was in a terrible car accident when he was thirteen so even though he's fifteen now he still has the iq and behavior of a five-year-old kid.

one day, you took soobin to the hospital for physical therapy. but he was crying and refusing, throwing tantrums.

"mama, i don't want to go there..! i wanna stay with mama.."
