Byun Yo Han emerged from obscurity through his supporting role in tvN's hit office drama, "Misaeng." In 2015, he delivered a compelling film performance in "Socialphobia," as Ji Woong, a young man who leads a mob of forum users down a slippery slope as they investigate the mysterious death of a despised internet personality.

He followed "Socialphobia" with the starring role in the romantic comedy, "Ex-Girlfriend Club," which yielded lackluster ratings. However, his appearance in the series eluded to his potential as a leading man of drama and film, with a bright future.
