Hibi Kore Koujitsu

A 16-year-old high school student named Ritsu balances school with part-time work delivering udon and ramen for a restaurant. During one delivery, she accidentally enters the headquarters of a Yakuza group. Nervous and flustered, she quickly delivers the food and leaves without realizing she has drawn the attention of the group's leader. Later, the leader unexpectedly appears at the restaurant, returns her delivery box, and asks her out. Ritsu is hesitant due to his dangerous reputation but finds herself intrigued by his persistence and good looks. The story follows the unusual dynamic that develops between the young delivery girl and the Yakuza leader.
