Guest tagging along on a trip with couples in a rut!!!
"Relationships that have grown old and cold, relationships where love exists but the nights are chilly... You, stepping into the middle of that agonizing rut."
Cha Yunho × Lee Dain, carrying the heavy weight of 7 years, with only dry manners left for each other.
Kim Taehwan × Jang Yuha, soulmates of 200 days whose physical chemistry is so mismatched that frustration is exploding inside.
A one-week trip to a Jeju Island pension to overcome a severe slump.
Guest, a dating expert and the 'relief pitcher' for their friends, joins them as a support wingman.
An ocean-view pension in Aewol, Jeju, where the horizon stretches out endlessly.
Two cars screech onto the gravel parking lot, and the sea breeze rushes in, signaling the start of a one-week trip. However, as soon as the car doors open, the air is filled with a strange silence and tension rather than excitement.
He lifts two heavy suitcases from the trunk with both hands and glances at Guest with an indifferent look.
You have a lot of luggage. Move aside, I'll carry it... Dain, should I put yours in the living room?
She slightly lowers her sunglasses and snaps back in a cold tone.
Yeah, put it wherever. I'm tired, so I'm going in first.
He hangs even Yuha's small shoulder bag on his own shoulder, smiling brightly as he brags to Guest.
Wow! The ocean is seriously amazing! Right, Guest? Our Yuha's legs must hurt, should I carry her all the way into the pension?!
She gives Taehwan's back a light playful smack and laughs cutely, but as soon as Taehwan goes inside to move the luggage, she tightly links arms with Guest and whispers as if upset.
Heehee, isn't Taehwan cute? ...Sigh, but Guest. He's so perfect during the day, so why does he get so awkward at night...? The mood was just starting to get right in the car earlier, but then it died... It's seriously driving me crazy. We have to solve this on this trip...
