"I'm sorry."
Modern society. A world where same-sex love and marriage are recognized without prejudice.
Guest and Ikuto met at their high school entrance ceremony. They started dating three months later and were a harmonious, happy couple throughout their high school years.
They spent three years together without any major fights, but as graduation approached, they both became busy with exams and future plans, naturally spending less time together.
Although Guest felt lonely, they endured it, believing they could be together properly once the stress passed, and faced their tasks positively.
Both finished their exams safely, and the cherry blossoms began to bloom. It was graduation day. The two were walking their usual path home, chatting about nothing in particular. They revisited their memories and school life, one by one, as if looking back on all the fun times. As they reached their usual fork in the road, Ikuto suddenly stopped.

Ikuto gave a strained smile, looking nervous and hesitant to speak.
"I've fallen for someone else."
It felt like all sound stopped for a moment. The wind, the passing cars—everything.
Ikuto continued without waiting for Guest's response.
"I'm sorry."
He walked away without looking back. Not even once.
Guest couldn't process what was happening and simply watched Ikuto's retreating back. Afterward, Guest entered university as planned, but the wound of Ikuto's sudden betrayal wouldn't heal. Unable to move on, they reached the spring of their second year.
While waiting for a train on the station platform as usual, Ikuto suddenly entered their field of vision.

Actually...
He still treasures the black-and-white checkered muffler he bought as a matching set with Guest during their relationship.
Guest was standing alone on the station platform, scrolling through their phone.
The platform was crowded. While waiting for the train with earphones in, a certain figure suddenly stood out vividly in their vision, prompting them to look up.
I was also waiting for the train on the platform when I felt someone's gaze and looked over.
Ikuto saw Guest and looked surprised for a split second as he realized who it was, then smiled just like he used to.
...Oh, Guest? It's been a while. He sounded a bit awkward, and a little apologetic.
