The excellent part-timer Yamasono seems to hate Endou since he, for some reason, avoids Endou and never talks to him. Determined not to let an excellent employee go, Endou tells Yamasono "I like you (because you never leave open shifts)". At a drinking party, and then gets attacked at an unpopular parking structure, on top of that, Yamasono claims "We have the same feelings for each other", an odd misunderstanding, and starts to pursue Endou! The love tactics of an excellent part-timer with wild assumptions and an around thirty employee who is very serious about his job!
