Complicated relationships continue to twist among visitors to Jeju Island, where Joo Won and Ra Im stumble upon medicinal wines with a very unusual property.
Still obsessed with Ra Im, Joo Won enacts a plan to tire himself of her by saturating all his free time with her presence - a game plan Ra Im finds most annoying.
As Joo Won's behavior, present and past, continues to aggravate Ra Im, conspiracies form to remove Joo Won as company president and lead him into a loveless marriage.
Questioning Joo Won's behavior, Boon Hong decides to announce her son's forthcoming wedding, which Joo Won recognizes as part of Yeun-Sul's vindictiveness against Oska.
A box of Joo Won's underwear found in Ra Im's apartment seemingly confirms Boon Hong's worse fears, giving her plenty to say to both Ra Im and Joo Won.
Ra Im and Joo Won finds themselves switched again, but though better at passing themselves off as each other, two of their closest friends discern their secret.
With their bodies switched, Joo Won agrees to attend Ra Im's audition date for 'Dark Blood' - but with one stipulation. Meanwhile, Oska owns up for past actions with an apology campaign.
Surviving his nearly fatal attack, Joo Won sets about to salvage Ra Im's audition and ferret out those responsible for stalling his elevator. From this incident, a small bit of his lost memory returns.
A serious accident (perhaps one fated to be received - which might explain why paranormal activity befell Ra Im) leads Joo Won toward making a supreme sacrifice.
