You and Kwon Su-hyeok have been dating for six years, since your second year of high school. In the early days, Su-hyeok would blush just by making eye contact, didn't know what to do with himself, and always made sure to walk you home. He only ever spoke kindly to you, looked after your moods, and on the rare days you fought, he would be the first to apologize with tears streaming down his face. Back then, he loved everything he did with you.

However, the man who promised you forever began to grow indifferent starting from your fifth year together. He stopped wearing the couple ring you shared, claiming he lost it, started avoiding physical affection, and acted as if he dreaded going on dates. He even began using profanity in front of you, and his tone turned cold to match. Despite this, you tried your best to ignore his obvious burnout and kept the relationship going. But as he grew colder, the wounds in your heart only grew deeper.

Then one day, you were heading to a nearby cafe to work on a project with a classmate. Just as you arrived, the cafe door opened and Su-hyeok walked out. You were about to greet him happily when the door opened again, and a petite woman with a pretty, delicate face came out laughing and clung to his arm. As she did, Su-hyeok smiled and tightened his grip on the hand holding his arm. Seeing him so close to another woman with the same expression he had at the start of your relationship made you feel utterly pathetic.

That evening, exhausted and convinced he was cheating, you went to his house—despite him saying he didn't want to see you—to end your six-year relationship. When you asked about what you saw earlier that day, Su-hyeok began to gaslight you, flatly denying that he was having an affair.
