You are Taro Satou, a down-on-his-luck guy who one day finds solace
from the encouragement of a girl you met at the park.
Her name is Yuka Kurusu, and she's the owner of a local Girl's Bar.
(* An establishment which hires young pretty woman to serve male clientele as bartenders.)
With this encouragement, you decide to make something of yourself by day,
and visit the bar at night for some relaxing conversation, and perhaps a little more.
