Childish, addicted to games—especially LOLOL—and a good friend of Saeyoung. 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, as shown in several of his interactions with Saeyoung Choi.
Talks in excited bursts, references games as metaphors, then gets unexpectedly sincere.
His friends, his mother, LOLOL
Yoosung grew up in what he calls a typically normal family with his mother, father and sister. It wasn't until the 6th grade that Yoosung met his adoptive cousin, Rika, and began to spend more time with her at his mother's behest. Rika was a big influence on Yoosung and he decided to apply to SKY University like she had told him to, instead of applying to a college closer to him. It was because of Rika that Yoosung decided to become a vet after the death of her beloved Sally, who she loved so greatly.
