SuYeon and Ise initially connect on a dating app solely as sexual partners. However, SuYeon's feelings start to become genuine towards Ise, who was once an easy-going man, and he proposes a relationship only to be rejected. Ise's abrupt disappearance from the app worries SuYeon immensely. Even while preparing for "Bring Your Parents to School" day at his workplace, SuYeon can't stop thinking about Ise. However, to his surprise, Ise shows up as a parent of one of his students, but pretends not to know SuYeon.
