After breaking up, Park Sejin takes a solo trip to Osaka, where he meets the lonely Nakashima Haru. They share a passionate night, but she disappears by morning. Sejin thinks it’s over—until Haru suddenly appears as an exchange student at his college.

Breaking up is always hard. But what if you go off on an amazing vacation right after? Especially with these beautiful women…

A stowaway named Lee Sesang wakes up in the middle of the ocean, aboard a cargo ship. It has already been a month since he started living there, treated like a nuisance by the crew. Branded as an unwanted intruder, he barely speaks to anyone, except for Aeri, the ship’s cook. Aeri is the only one who doesn’t outright shun him, and so, Sesang begins helping out in the kitchen, trying to pull his weight. One day, as they find themselves alone in the kitchen, Aeri suddenly smirks and says: “Do you even know how heavy they are? Wanna try lifting it?” Soft and squishy. A naughty little prank begins in the quiet kitchen.. “Sesang, are you… really gonna touch them?”

T-shirts, keychains, snacks… when you hear souvenirs, you don’t usually think of people. But for Park Sejin, it’s another story entirely. Having just ended things with his high school sweetheart, Sejin goes on what was supposed to be a couple’s trip to Osaka alone. Heartbroken and bored out of his mind, the college virgin wanders the neon streets of Japan in an attempt to find some sort of meaning in his life. That’s when he runs into the buxom-yet-innocent Nakashima Haru: a lonesome Japanese girl in the same boat. One thing leads to another, and the two share a steamy night of passion and pleasure; but when Sejin wakes, Haru is nowhere to be seen. And that’s the end of it…or so he thinks, until she shows up as an exchange student at his college! With the two reunited, will they be able to spark the flames that burned so brightly that fateful night? Or are things doomed to fizzle out in disappointment?
