Seventeen-year-old Joonho Suk just had the best day of his life. He finally got the guts to ask out his big crush, Sae-un, and she said yes!! But after floating home on cloud nine, he found... his family packing up to move to Seoul?!

Now tossed into a big new city and lovesick for the girl still in Suwon, Joonho runs into weird characters at every turn. First there's the young girl who speaks a strange language and has enormous strength, then a wayward cat causes another-Hanami-to wipe out on her bike! She's okay, but Joonho might not be once her massive grandfather shows up and thinks he's to blame...!

Hanami's sweet nature quickly charms Joonho, and he discovers that his new school, including a self-styled blonde Casanova, is already abuzz over his cute Japanese neighbor. But what about Sae-un? And what on earth is the Babe Patrol Research Center?!
