I don't see a ring on your finger | Sunsun
Sunghoon's older sister is getting married, and he's under pressure from his family to bring a serious partner to the wedding. Tired of dodging questions about his love life, he impulsively asks his best friend - the ever-charming Sunoo - to pretend to be his boyfriend for the weekend.
Sunoo agrees, even though it secretly breaks his heart. He's been in love with Sunghoon for years, but never dared to say a word.
