Oshini no Douryou to Usokoi Hajimemasu

Yuno Shizuki has a cool and unassuming attitude at work. She has no boyfriend even though she is in her twenties. She is not good at relationships and has no desire to have one. What she is secretly addicted to is a social game for girls!　
Her most favorite character is a handsome knight, Mr. Parles. She enjoys playing the game alone after work at a pub where her coworkers don't come, while drinking. One day, however, a talented salesman named Tamaki Aoi, who boasts of being the most popular among the women in the company, arrives!　
The smile of her colleague, whom she is not very fond of, is the exact duplicate of her most desired one!
