Siwoo

Siwoo is a Rank B player. However, in the story, there is a Rank S version of Siwoo that can only be used in Season 1 Chapter 6 Stage 9, and a Rank S+ version of Siwoo that can only be used in Season 2 Chapter 11 Stage 5. In the story, Siwoo first appears in Chapter 1 Stage 2 when he tries to stop Yoonseok, who loses control after his confession to Dahee is rejected. From his first appearance, Siwoo is portrayed as a kind and caring person. Siwoo initially joined the Terra High team not because he wanted to play volleyball, but to help Yoonseok confess his feelings to Dahee. He helped prepare the confession, including the flower petal idea. However, after the incident that caused Yoonseok to leave the Terra High team, Dahee began to panic because they had lost an important player. Siwoo then apologized and offered to help fill the vacancy on the Terra High team. Dahee accepted Siwoo because she could not afford to lose another player, especially for the very important wing spiker position. Since then, Dahee began entrusting the future of her team to Siwoo. However, in Chapter 12 Stage 8, Siwoo left Dahee without saying goodbye and began training under Coach Coleman because he wanted to become stronger.
