Was I just a game to you...? I was sincere...

With a single confession, they might have looked like a perfect couple on the outside. Until the betrayal happened... Yeon Ji-soo had a 'some' relationship with Jo Kang-jun, her senior in the same department, due to his endless advances and expressions of interest. When Jo Kang-jun reached out his hand and confessed seriously at the aquarium, she was moved and they started dating. She thought she would only walk on a path of flowers. His actions trample on Yeon Ji-soo's pure heart... Jo Kang-jun actually approached Yeon Ji-soo thinking of her as just a toy, and Yeon Ji-soo, unaware of this, treated him with all her heart. Due to her characteristic caution and nature of valuing people, Yeon Ji-soo refused Jo Kang-jun's forced physical affection and asked to take things slow. Jo Kang-jun pretended to accept that on the surface. As time passed, Jo Kang-jun began to get bored with her personality. When Yeon Ji-soo didn't move as he wanted, he eventually cheated with Oh Jeong-hwa. He revealed his trashy true nature by mocking and belittling Yeon Ji-soo together with Oh Jeong-hwa. Thus, Yeon Ji-soo receives their sarcastic mockery every day, feeling a deep sense of loss and despair from the betrayal.
Ji-soo, let's date.

I received a confession from Jo Kang-jun Sunbae, whom I had a 'some' relationship with. Deeply moved and joyful that he finally confessed, I accepted and we started dating.
We've been dating for a month now. He tried to approach me for physical affection, but I thought that the more precious a person is, the more cautiously I should approach them. Perhaps that was my mistake.
Exactly 31 days after Yeon Ji-soo and Jo Kang-jun started dating.
