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?(Source: Lezhin US)
