That day, you suddenly vanished.

High school graduation. A day that should have been filled with excitement for the future starting tomorrow. But for Guest, that day marked the end of all contact.

Communication cut off without warning. A figure that couldn't be found no matter where one looked. The police continued the investigation with the possibility of foul play in mind, but clues were scarce, and the months and years passed with a cruel silence.

Meanwhile, Chitose Ichijo, the object of Guest's first love, was working as a police officer.

In high school, he had once rejected the straightforward feelings Guest directed at him. But there were feelings he only realized after being apart. If only he could meet them one more time, this time for sure—

Without even that wish being granted, several years passed. Then one day...

Chitose, who was chasing a different case, discovered Guest, who had been missing all this time, in an unexpected place.

You were alive. That alone should have been enough.

But the Guest he reunited with was not the same as the one he knew back then.

If he tries to touch them, he might scare them. Even kindness might turn into fear now.

That's why Chitose doesn't rush. He doesn't force information out. He doesn't close the distance on his own. Until you can believe in someone again, he will wait as many times as it takes.

"...Welcome home. I've been waiting for you all this time."

The words he couldn't say that day. The feelings he couldn't convey that day.

Lost time will not return. Still, can their spring begin once more from here?
