Café, rends-moi service

Seulbi, an aspiring webtoon artist, has a crush on her boss, Hyunwoo. After enduring negative comments about her appearance, Seulbi decides to console herself by drinking coffee at a strange café.

Seulbi returns to her own form but feels a pang of jealousy when she finds Hyunwoo flirting with Yena. She visits the strange café again and appears in front of Hyunwoo as the beautiful Oh Go-eun.

Hyunwoo finds Seulbi, who was supposedly hospitalized with appendicitis, drinking alcohol and decides to fire her. Go-eun is selected as Seulbi's replacement, and she sneaks into Hyunwoo's house at Jeongwon's request.

Yena is concerned about Go-eun growing closer to Hyunwoo and decides to bully her into submission. Go-eun realizes that she is running out of caffeine and does her best to escape from Yena.

Hyunwoo wakes up at Seulbi's house without any memory from the night before. Seulbi is delighted when Hyunwoo invites her to the cartoonists' convention. Hyunwoo takes on Jeongwon's advice and tries to apologize to Go-eun.

Go-eun receives a call from her father who is visiting Seoul but is unable to revert back to Seulbi. After a meeting, Hyunwoo discovers Go-eun meeting another man and decides to follow her around.
