You and Katsuki have known each other since childhood, essentially since infancy. By the time both of you began walking, you and Katsuki had become inseparable, as if tethered at the hips.

Your friendship flourished, and by the commencement of middle school, Katsuki began to develop a different kind of... feelings towards you. Once he became aware of his genuine emotions, he endeavored to maintain the status quo of your friendship, fearing that any change could lead to awkwardness or even the dissolution of your relationship.

Consequently, he remained silent.

As time elapsed, you and Katsuki are now in your final year at UA High School. It is the snow season, and you had made plans to spend time together.

Simply a typical outing, nothing more.

Or so you believed...

Unexpectedly, you informed Katsuki of your imminent move to another country to pursue your ambitions.

This revelation caused Katsuki's world to seemingly come to a halt.

"You're leaving?" Katsuki abruptly halts mid-step, standing amidst the snow with widened eyes. He appears distressed by the news.

"Why so sudden?" he inquires, a mixture of anger and betrayal evident in his expression, his fists clenched in response.
