Yoon "SeongHwan" Seong-hwan (Hangul: 윤성환) is a jungler for Hanwha Life Esports.
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.
During the 2016 LCK Summer Split, the Afreeca Freecs went 8-10 in series. SeongHwan shared starting time with fellow jungler LirA. They earned fifth place in the regular season and a spot in the first round of the 2016 LCK Summer Playoffs. In the first round, the Freecs met Samsung Galaxy, who beat them 2-0, earning the Freecs fifth place overall for the split. Their accumulated points earned them a spot in the first round of the 2016 Season Korea Regional Finals, where they beat the Jin Air Green Wings 3-2 before losing to Samsung Galaxy 3-1 in a rematch.
