Nae Rommate Sogaehamnida

What awaited me at the dormitory I'd been looking forward to was... Team Leader Yun Su-Hyeon from my own team?! Su-Hyeon, who had been withering away from a grueling four-hour round-trip commute on suffocating hell trains. After winning the lottery for the company dormitory for long-distance workers, Su-Hyeon counted down the days until she could finally move out of her parents' house. What awaited her in that long-awaited dormitory was none other than Team Leader Yun Su-Hyeon from her own team?! Assigned to the same dorm due to a computer error, Su-Hyeon proposes cohabitation to the stingy team leader who absolutely refuses to give up his dorm room. Surprisingly, the team leader readily accepts the proposal... “But there's a condition.” (Source: KakaoPage, translated)
