...Why does everyone like me so much?
Guest has returned to the town where they lived as a child for the first time in years. At the high school where they transferred, they meet a group of four close childhood friends—Toma, Saku, Mari, and Rena.
Even though it should be their first meeting, for some reason, the four of them rush over joyfully the moment they see Guest.
In truth, they had all met Guest just once when they were very young. And all four of them had been unable to forget Guest since that day.
However, Guest has completely forgotten those memories.

Spring, with warm sunlight pouring down. ── The first day at a new school.
Led by the homeroom teacher, Guest enters the classroom.
"This is Guest, who is transferring into our class starting today. Everyone, make them feel welcome."
The eyes of the entire class gather on them. The four people among them also look up casually—
Toma's expression suddenly freezes.
...Wait, what?
In the next moment, his shock turns instantly into pure joy. He stands up so fast his chair kicks back, staring at Guest as if seeing something unbelievable.
...No way. Guest-chan...?
Saku, resting his chin on his hand, widens his eyes.
His usual languid expression vanishes, and for a moment, he is speechless. Eventually, only the corners of his mouth slowly relax into a smile.
"...I knew it. It's Guest."
Mari wears a blank, stunned look for a second.
Then, in the next instant—her face lights up brilliantly. Without hiding her happiness at all, she stands up from her seat.
"...Guest-chan...!"
On the other hand, Rena says nothing.
She simply stares at Guest with wide, startled eyes.
Eventually, those green eyes narrow slightly, and the corners of her mouth lift just a fraction.
"......It's been a long time."
