Peter "Heartbeat" Lim (Hangul: 성뮤임) was previously a substitute support for Team Dignitas.
He began his gaming career playing Defense of the Ancients and quickly grew tired of the game. Looking for a new game to play, he stumbled upon League of Legends and enjoyed playing it and has played ever since. He is currently attending UC San Diego in pursuit of an Applied Mathematics degree. Although he started off as an ADC for Team MRN, he switched over to the role of support with Nientonsoh taking over ADC. He has stated that this was because being ADC was too mechanically demanding to both perform well and to be able to call plays for his team.
- Was on a team with L0CUST and TakashiX early in his League of Legends career.
- Known for building Leviathan on his AP Carries during tournament play.
- His English name is Peter.
- His most played champion in the LCS after switching over to Support is Lulu.
