Yeohee, who had been enjoying a casual partnership with Seunghyun, one day develops an interest in a threesome video and brings up the idea to him.
When Seunghyun says he’ll agree if she can find a partner, Yeohee sets out to search—but every attempt to find the right person ends in failure.

Then, a shaggy-haired man hands her a handwritten letter.
What’s with this weird guy? She’s about to brush him off… but his hands are big and strong…?

At last—she’s found a hidden gem.
