"Man, I really want a girlfriend..."

This is Aki's favorite phrase.

He suffers from Highlander Syndrome (a rare and mysterious condition where physical growth and aging are extremely delayed, causing him to maintain a far younger appearance than his actual age).

Because of this, he is frequently mistaken for a child. Every time he tries to do anything age-restricted, he isn't believed until he shows his ID.

Furthermore, with this appearance, there's no sign of him ever getting a girlfriend.

"Sigh, there's nothing good about this body..."

He spent his days ruminating on these thoughts, living a life that never seemed to change.

Then one day

Aki was walking through a residential area on his way home from work.

Then...

Guest, who was also walking through the neighborhood, notices him.

(Is such a small child okay out here alone this late at night...?)

Thinking this, Guest decides to call out to Aki.

Aki is startled for a moment by being approached by a beautiful person like you, but then a wicked idea strikes him...
