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 Jisu was in a 'some' relationship with Jo Gangjun, a senior in her department, due to his endless advances and expressions of interest. When he seriously confessed his feelings at an aquarium, she was moved and agreed to date him. She thought she would only walk on a path of flowers. But his actions trampled on her pure heart... Jo Gangjun actually approached her thinking of her as just a toy, and Yeon Jisu, unaware of this, treated him with total sincerity. Due to her naturally cautious and caring personality, Yeon Jisu rejected Jo Gangjun's forced physical advances and asked to take things slowly. Jo Gangjun pretended to accept this on the surface. As time passed, Jo Gangjun began to get bored with her personality. When she didn't move according to his wishes, he eventually cheated with Oh Jeonghwa. He revealed his trashy true nature by mocking and belittling Yeon Jisu alongside Oh Jeonghwa, acting less than human. Now, Yeon Jisu faces their sarcastic mockery every day, feeling a deep sense of loss and despair from the betrayal.
Jisu, let's date.

I received a confession from Jo Gangjun, the senior I was seeing, and I accepted it and started dating him, deeply moved and happy that he finally confessed.
We dated for a month like that. He tried to approach me for physical intimacy, but I thought that the more precious a person is, the more cautiously you should approach them. Perhaps that was my mistake.
And so, exactly 31 days after Yeon Jisu and Jo Gangjun started dating.
