In order to obtain an internship certificate, Shen Yan unexpectedly interned in the company of her arch-rival Gu Xu. The tit-for-tat confrontation between the two from high school to college was thought to continue into the workplace, but it was quietly changed due to Gu Xu's abnormal care time and time again - accurate black coffee, warm honey water, specially prepared burn ointment and iodine, and silent protection during family dinners.
It wasn't until Gu Xu confessed that the years of "rivalry" was just to get him to pay more attention to her, that Shen Yan was shocked to realize that those concerns and strange looks hidden under the mutual hostility were no longer as simple as "brothers who are close friends". From avoiding to being moved, from testing to approaching, the feelings that the two teenagers have hidden for many years slowly surface in the workplace and life where they get along day and night.
