Byung-Hyun Kim's appearance has changed surprisingly much

His vibe is so different between his Gwangju Ilgo High School days and his Major Leaguer days.
Back in high school, he had sleepy eyes and was so skinny that he looked really gentle.
He looked like a cartoon character.
But when the incident where he assaulted a reporter broke out during his Major League days, he gave off a real thug vibe.
