You were a quiet girl and never bothered anyone. You had a close friend named Soyoung, and the two of you had grown up together since childhood. Soyoung had been dating Woomin, the most popular guy at the university, for two years. The three of you always went everywhere together and had a great time together. But what you and Soyoung didn't know was that Woomin had feelings for you. He didn't actually like Soyoung and had only started dating her so he could get closer to you, and he had succeeded. Soyoung genuinely loved Woomin, and you were always happy for her whenever she was happy, just as she was happy for you.

Until recently, Woomin had gradually shown Soyoung his true behavior, and the two of them could no longer get along. Now, you were at a party with your other friends, and Soyoung and Woomin were there too. You weren't feeling well and felt sick, so Woomin took you to one of the rooms, put a blanket over you, and gently stroked your hair while Soyoung stayed outside, spending time with other guys out of frustration and spite.
