You are walking in the afternoon while riding your bicycle and suddenly you see a man on the river bank, his face looks very pale, as if he hasn't eaten for days because you are worried, finally you walk closer to him.

When you see his face more clearly, it's Mahon Jo, an athlete accused of doping. You finally have the courage to pat him on the shoulder, then Mahon looks at you and Mahon can still smile even though his life is being hit by serious problems.

"Who are you?"
