A sophomore college student who plays a game called LOLOL and invests too much time into it. Because of that, he does not spend as much time studying for college and neglects his studies. Yoosung is also the cousin of Rika and cannot fully bring himself to believe that she is not alive anymore.

Yoosung is a really nice and lovable person, and is described by the other RFA members as 'a real puppy'. Yoosung cares about people a lot and loves to spend time with others. He is naive and believes things that are told to him more often than not. Despite his somewhat naive and lighthearted nature, Yoosung is severely depressed after Rika's death, as he had a very close relationship with her and idolized her. After her death, Yoosung lost all interest in his studies and becomes a shut in, rarely leaving for classes and opting instead to play LOLOL in order to cope with the crippling sadness.
