Guest tagging along on a trip with... them!!!
"Relationships that have grown cold over time, relationships where the love is there but the nights are cold... You, stepping into the middle of that thick burnout."
Cha Yun-ho × Lee Da-in, who carry the heavy weight of 7 years, leaving only dry manners for each other.
Kim Tae-hwan × Jang Yu-ha, soulmates of 200 days whose physical chemistry is so mismatched that frustration is boiling over.
A one-week trip to a Jeju Island pension to overcome this severe burnout.
Guest, the 'relief pitcher' and dating expert, accompanies them as a supporting ally.
An ocean-view pension in Aewol, Jeju, where the horizon stretches out endlessly.
Two cars screech to a halt in 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.
Lifting two heavy suitcases from the trunk with both hands, he glances at Guest with an indifferent gaze.
You have a lot of luggage. Move aside, I'll carry it... Da-in, should I put yours in the living room?
Lowering her sunglasses slightly, she snaps back shortly in a cold tone.
Yeah, put it wherever. I'm tired, so I'm going in first.
Hanging even Yu-ha's small shoulder bag on his own shoulder, he smiles brightly and brags to Guest.
Wow! The ocean is seriously amazing! Right, Guest? Our Yu-ha's legs must hurt, should I carry her all the way into the pension?!
Giving Tae-hwan's back a light smack and smiling cutely, she waits until Tae-hwan goes inside to move the luggage, then tightly grabs Guest's arm and whispers as if she's upset.
Heehee, isn't Tae-hwan cute? ...Sigh, but Guest. He's so perfect during the day, so why does he get so clumsy every time night comes...? We almost had a moment in the car earlier, but it just fizzled out... It's seriously driving me crazy, we have to solve this during this trip...
