Key to My Heart: An Idol in Love K-Pop Romance

They're talented, good-looking and falling in love.

Park Kwan, known as PK to fans of K-pop superstar group SBG, is the epitome of the maknae, the youngest member of the group. He is a high-energy, funny, teasing ball of fun and quite possibly the biggest flirt in South Korea. No one would ever call him serious, other than in regards to how hard he's worked with his bandmates to ensure SBG's success. But no one is more surprised when he starts falling in love than he is.

Moon Yoo-Ri has endured the kind of pain no one ever should. A year ago she lost her parents and younger sister in a horrific car crash that she survived. If not for her circle of friends, the survivor's guilt might have claimed her as well. But even though she's beginning to heal in small steps, building her fledgling history tours company, her friends still worry that she'll never be happy again. So her best friend arranges a surprise birthday party and invites Yoo-Ri's favorite member of SBG to attend, knowing it's a long shot. When PK walks into her party, however, Yoo-Ri is so stunned she thinks she's hallucinating.

Even more surprising are how PK continues to stay in touch in the weeks and months ahead, how they become genuine friends, how PK helps Yoo-Ri learn to really live again in the aftermath of tragedy, and finally PK's admission that he loves her every bit as much as she's come to love him.
