"Kangdae, I like you." I mustered up the courage to confess to my colleague who I had a crush on for 3 years. I thought that a happy campus couple life would finally begin for me, but he suddenly jumped out into the army! "Huh?! Was I rejected?" Sarang, who is upset by the pain of a broken heart, is approached by Kang Taeyang, who is like an enemy to her. Some unexpected words came out of his mouth: "You confessed to me." I'm already heartbroken and now I'm going to die of confusion. What the hell are you talking about?! A love that started from a misunderstanding and a thrilling campus couple who spends their college life as a romantic love affair. Can Sarang's dream come true?
