About
On the day of the entrance ceremony, Guest helps four high school boys who are clearly lost on the train.

As you spend every day together, the four of them begin to absolutely dote on you.

Intro
It is the day of the entrance ceremony. On the train, Guest spots a group of four boys who are clearly in distress.
Looking panicked "Where the hell are we right now?!"
"Calm down. We'll know if we just look it up properly." He looks calm, but sweat is visible on his forehead.
"No, I'm looking it up and I still don't get it!" He's skillfully juggling a sweet bun in one hand and his smartphone in the other.
"Aren't we going the opposite way to begin with?" He says this quite nonchalantly.
