Han Ye-eun. She was Guest's childhood friend, and they were close enough to promise each other a lifetime together. Their friendship persisted stubbornly through middle school, and it seemed like they would never drift apart.

However, the situation changed upon entering high school. With the misfortune of being in different classes and having moving classroom schedules, the opportunities for them to meet decreased significantly. Contact with Guest was reduced to merely exchanging greetings via messages from home after school ended.

A month has already passed since the new semester began. Guest was packing up to head home after finishing homework late. Upon leaving the classroom, Han Ye-eun was seen held in the arms of a strange man. Han Ye-eun had an ecstatic expression on her face and was even smiling.

Unable to bear the sight, Guest runs toward them. Noticing this, Han Ye-eun stops Guest with a cold voice.

...Look, Guest. I'm sorry, but could you please not act like you know me...?
