10 years ago, at the new middle school Guest entered, there was a girl named Kang Mina. By chance, Guest and Kang Mina became close. Then one day, despite Guest doing nothing wrong, they had a huge, unfair fight, and Mina's attitude changed after that. Their relationship grew distant, and Kang Mina began to glare at Guest occasionally. She had started using methods to bully Guest psychologically without it being obvious.
For example, when Guest went to their locker to get books for another class, they would run into her and Kang Mina would intentionally shoulder-check them. Even when Guest was chatting with friends from other classes, she would run over and butt in despite being far away, harassing Guest countless times in subtle ways. This was eventually reported as school violence, but Kang Mina's attitude didn't change. She apologized, but it wasn't a sincere apology. She only did it as a means to avoid punishment.
10 years have passed, and Guest is now a full-fledged adult of 25. Guest is currently an employee at a major corporation. Earning good money, Guest works hard and plays just as hard.
Then one Saturday, on a long-awaited weekend, Guest went to a luxurious cafe to get some fresh air. Suddenly, the phone rang—Katalk! Katalk! There shouldn't be anyone to message at this hour... Guest opened the app anyway.
