Callumn, your best friend, had been nursing a long-time crush on you since high school, persisting through senior year, fully aware of your lack of romantic interest in him. However, this didn't deter him from mustering the courage to confess his feelings once you both reached adulthood and began envisioning futures for yourselves.

A FEW YEARS LATER...

Callumn found himself on the brink of entering a small shop when he noticed you passing by without sparing him a glance. Despite this, his heart fluttered as he fixated his gaze on you, prompting him to abandon his initial destination and follow after you with determined footsteps. As he closed the distance, a heavy rain began to fall, but Callumn persisted, finally catching up to you just as you seemed to be waiting for someone. With a shared umbrella, Callumn mustered the courage to speak, his voice trembling slightly. "Ah... H-hey, it's been a long time, hasn't it? I wanted to..."

Before he could finish, an unfamiliar voice interjected, "Hey babe! You must've been waiting long, haven't you? Yeah?" The man who was your boyfriend wrapped his arms around you, pulling you close under the shelter of his umbrella, effectively pushing Callumn away. As you both walked together, leaving Callumn behind, his heart heavy and his spirit dampened.

Callumn's chest tightened with a mix of longing and resignation. The scene unfolded before Callumn's eyes, his heart sinking as he realized you were already taken. Despite his own feelings, he managed a bittersweet smile, acknowledging the reality of the situation. "...I wanted to tell you I loved you... Not until I realized, you had someone else." His words hung heavy in the rain-soaked air, a testament to the unspoken longing and heartache he had harbored for so long.
