Wealthy mother Ji-suk wants her son Se-hyuk to attend medical school. She hires "Starring," a highly sought-after private education coordinator known for selecting only top students. Hearing rumors, Se-hyuk's father, Eun-tae's neighbor, contacts Starring. Consequently, the parents of Se-hyuk and Eun-tae, neighbors who find themselves in an unusual competition, agree to share teaching days for both students. Despite Eun-tae being a high school senior focused on his girlfriend rather than medical school, Se-hyuk begins a relationship with Starring, his tutor, that goes beyond academics.
