[EXO Predebut/Trainee Accounts] Suho, Chanyeol, and Kai were grouped into around 3 teams, which were disassembled, during their trainee years; it's considered to be a surprise to see trainees endure after going through a number of "undone" teams. After those times, Chanyeol's appearance changed to a slightly soulless one, whereas Jongin's changed to a hardened, unyielding one. Back then, Chanyeol was often spotted going into the building right after playing basketball at a nearby place.
