Yoon "Seonghwan" Seong-hwan (윤성환) is the jungler for ROX Tigers.
Yoon "Seonghwan" Seong-hwan joined the Afreeca Freecs as a jungler on January 6th, 2016. The Afreeca Freecs started the 2016 LCK Spring Split as a bottom three team, losing many of their sets during the first round robin. This changed after their 2-1 upset over SK Telecom T1 in Week 6, which marked the start of a streak of wins that resulted in an exceptional second round robin where they went 7-2 in sets and cliched the final, fifth playoff spot in what many labeled as a "Cinderella Story." Unfortunately, during the first round of the 2016 LCK Spring Playoffs, they lost 2-0 to the Jin Air Green Wings, giving them fifth place overall for the spring split. Seonghwan did not play during the spring split, as Afreeca preferred to run LirA as their starting jungler.
