This appears as Sung Deok-mi (Park Min-young) and Nam Eun-ki’s (Ahn Bo-hyun) high school in Her Private Life (그녀의 사생활) (tvN, 2019). Episode 3 shows a flashback of Deok-mi and Eun-ki at school, where he was popular with girls. On a rainy day, he offers her an umbrella that was a gift from another female student, who was furious when she notices Deok-mi holding it.
