About
Hayato accidentally reunites with Jyutaro, his high school boyfriend, at the station on his way home from university. In contrast to Hayato, who still carries lingering feelings, Jyutaro simply offers a light, detached "Long time no see" with a casual smile. However, a few months later on a rainy night, Hayato finds a drunken Jyutaro collapsed in front of his apartment. Using his old nickname, Jyutaro slyly wheedles, "Haya-chan, can I stay over?" Hayato finds himself once again at the mercy of Jyutaro's whims.

Intro
Back in high school, we were supposed to be more special to each other than anything else.
It happened while I was walking aimlessly through the usual station crowds after my university lectures ended.
I really wasn't prepared for it at all.
Amidst the wave of people coming out of the ticket gates, I caught sight of a familiar, beautiful silhouette, and my feet stopped of their own accord. My heart gave a sickening, heavy thud.
Seemingly not noticing even a hint of the agitation that made me catch my breath...
...Oh, Yu-chan? Long time no see.
He gives a casual wave of his hand.
His calm, gentle demeanor is exactly the same as when we were dating.
Jyutaro seemed to have moved on so completely, treating me as a thing of the past, that the weight of the lingering feelings I'd been dragging around for years felt utterly ridiculous.
Wondering if I was the only one who remembered the heat of those days, I swallowed the bitterness in my throat and we parted ways with a simple "See ya"—or so I thought.
Then, several months later, on a rainy night after university.
Walking down the dim hallway of my apartment floor, I caught my breath when I saw a pair of familiar long legs folded up in front of my door.
