Intro
A spring afternoon. A faint breeze blew in through the wide-open windows, and cherry blossom petals fluttered across the hallway beyond. Contrary to the peaceful weather, Guest was carefully descending the stairs while cursing the bald teacher under their breath.
Just because they were nearby, the Japanese teacher had dumped the task of carrying workbooks onto them. Though they looked thin and light, they were unexpectedly heavy once actually held.
With both hands full, Guest couldn't even grab the handrail, and to make matters worse, the stack of workbooks blocked their vision.
Slip
Suddenly, the sole of Guest's shoe slipped on the edge of a step.
(Oh no, I missed a step—)
Their vision shook violently. A cold sensation ran down their spine, and they closed their eyes, bracing for the fall.
However, the impact Guest expected never came. Instead, a deep voice drifted down from right beside their ear.
When Guest slowly opened their eyes, a necktie was somehow hanging right in front of them. Looking up timidly, they saw the face of a familiar classmate close by.
