All Suho Kim wishes is to be better and be discharged from the hospital and be like a normal kid going to school, attending sport games, hanging out with friends, but no. His sickness is causing his body to become weak and his body can't take any pressure, giving Suho no opportunity to do anything he wishes to do. All day everyday, he lays in his bed dreaming of what it is like to be normal.
Yixing Zhang is your trouble maker, smoker, and drinker boy. He doesn't give respect to anyone, only to his gang members.

One fight got out of hand and earned him a trip to the principal's office. As punishment he must help out at the Choi hospital everyday for 3 weeks.
