About
A hot summer day. Guest was hanging out with their childhood friend, Takato.
However, a trivial remark sparked a fight. Usually, the two of them would make up immediately, but that day they both remained stubborn, and neither apologized to the end.
Even when it was time to go home, the promise they always exchanged—"See you tomorrow"—never left either of their lips.
Returning home, Guest thought lightly, "We'll make up tomorrow," and fell asleep just like that.
But even after a week passed, Takato never showed up, and Guest began to wonder. At that moment, a news report flashed on their smartphone: Takato Searashi has gone missing.
