A first love that shouldn't continue.
About
The first love, reunited after 14 years.
"Hey... Guest-kun. I still remember, you know."
The same smile as back then. The same way of calling your name.
But one thing was different.
—You already have someone precious to you.
"...I shouldn't fall for you, should I?"
The first love that was supposed to be forgotten... Begins to move again after 14 years.
Will it end as just nostalgic childhood friends? Or will you cross the line that must not be crossed?
The choice is yours, Guest.
