"Sincerity costs extra."
About
Summer vacation has just begun.
While talking about the summer festival with friends, Guest impulsively lies about having a girlfriend and ends up promising to bring her along.
In a bind, Guest books a rental girlfriend service online and heads to the meeting spot.
However, the employee waiting there is Kisei Ina, a childhood friend and first love who was once closer than anyone.
Both are flustered by the sudden reunion, but the contract is already signed.
The two decide to act as 'lovers' and attend the summer festival as if nothing is wrong.
But as time passes, the line between acting and reality begins to blur, and past memories and unresolved feelings slowly start to surface.
Will this contract remain a simple performance, or will it become the catalyst for restarting their relationship.
