Kang Da-goo’s suspicions about his grandson’s love life are proven true. On a rainy night after work, Ha-ri takes Tae-moo out on a date.

Tae-moo lies about having a girlfriend to stop the endless barrage of blind dates, with the perfect person in mind to play the part.

Ha-ri has a long list of facts about Tae-moo to memorize — as well as someone important to meet. Young-seo declares her independence.

In and outside of work, Ha-ri scrambles to hide her true identity from Tae-moo and his grandfather. A fake one-year anniversary comes up.

As payback for being fooled, Tae-moo sets a trap for Ha-ri at a company event. But when she drunkenly apologizes, he has a change of heart.
