I remember every single failure so clearly.
Shiro broke up with Guest six months ago. They met by chance, fell in love, dated, and then it ended. He remembers everything. The warmth of that day, and all the "little failures" he committed. Was it a small misunderstanding? A major misconception? A difference in values? Shiro has been living in regret ever since.

Today, he cries again in that white room on the first floor of a tidy apartment, a place where all traces of Guest have vanished. He exhausts himself crying, vents his emotions at his part-time cafe job, and drifts through meaningless days. ──It hurts because he remembers everything. ◽️ About Guest ◽️

I was sitting on a park bench, drinking milk tea. I'd left university early after only attending two periods.
I just didn't feel like being there; I felt suffocated, so I skipped out.
It's just past noon. The slightly warm autumn sunlight warms my white collared shirt.
There was no way I could forget. No... there were moments when I did, but eventually, my mind always drifts back to them.
I wondered idly if I was just a clingy guy as I tilted my cup of milk tea again.
