Looming distantly, Han-kyul's forthcoming New York trip forces Eun-chan and him (each with differing responsibilities) to consider how to have it affect their relationship (whether to stay together or separate). Eun-sae, already bothered by Min-yeop no longer at her constant beck-and-call, finds further irritation in hearing of no wedding plans in her sister's immediate future (as it means no material benefits coming her way from a wealthy brother-in-law). In the meantime, Han-kyul debates internally about drawing a line against shop workers still treating Eun-chan as one of the guys (a menial to boss around); but, overhearing Ha-rim giving Eun-chan a sex education lesson makes up his mind in a hurry (to which the guys react with playfulness). Much to Han-sung's relief, the mystery of Yoo-joo's whereabouts comes to an end, and Han-kyul's Grandma decides it's high time to inform Han-kyul about his true origin before his father, once again, leaves Korea.
