Reception
Impact
In episode 22 of the series, Lee visited Yeonsung University. During the lunch break period, he discovered the university cafeteria served only 2 types of dishes, and he listened to the dissatisfaction from the students attending the university regarding the university cafeteria's menu. After the episode was aired, an online community post shared that the university cafeteria's menu had increased from 2 types of dishes to 40 types of dishes. An official from the university shared that Lee (and the series) had played a role in executing this change for the new semester.[5]
Controversy
On October 5, 2023, after the release of episode 35 of the series, many have posted on Korea University's online community regarding the series' filming staff while filming of the said episode was done in the university. Those posts had stated the staff's abuse of authority such as restricting the university's undergraduates from entering the student center, and prohibiting talking among students in the venue while filming. Subsequently, many have requested, through the uploaded video's comments section, for an apology from the series' production team, but had been blocked. This controversy was spread out to various other online communities, with several students from other universities sharing their negative experiences with the filming staff while filming in those universities.[6] The next day, the series' production team issued an apology as a pinned comment on ootb Studio's latest uploaded video, and later uploaded another apology as a community post on ootb Studio's YouTube channel. As a result of this controversy, a new episode was not uploaded on October 12 and would return the following week after reorganization.[7]
Spin-off: Jeongwating
During Season 7 of the series, episodes 101 and 106 were spin-off episodes which featured male and female students from different universities gathering to socialize and potentially find a romantic partner. These episodes had received positive and enthusiastic responses, hence on December 2, 2025, ootb Studio announced that this group date spin-off titled "Jeongwating" (Korean: 전과팅) will officially become a regular show beginning January 2026, with new episodes releasing every alternate week during the school winter break.[citation needed]
