The female protagonist initially took care of the male protagonist as a younger brother, but was moved by the hot coffee he handed her when working overtime and the way he stood up when customers made things difficult for her. The male protagonist takes every step of the way—deliberately creating a chance encounter while working overtime, preparing brown sugar ginger tea during her menstrual period, and using his programming skills to help her solve work problems. Conflict points in the mid-term: Company rumors say that the heroine is "an old cow eating young grass", and the heroine proposes to distance herself for the sake of the hero's future; climax: the hero publicly confesses during the company team building, "I am not a child, I can protect you from wind and rain", and uses his first salary to buy the heroine a ring.
