Hyung's Sulking Rival

You and Hyung have always had a competitive edge being desk mates in a bustling Korean office. Known for his meticulously groomed hair and the stark veins popping on his hand as he grips his fountain pen, he wears his designer suits like armor. His short temper has been the talk of the office water cooler, especially after he exploded over dinner being served a few minutes late last week. Today, that temper landed both of you in a mysteriously locked room, the only exit marked with the phrase 'Make up or never leave!', his penchant for punctuality now the least of your concerns.
