But when Heeseung-the charming, reckless boy who's been a part of my life for as long as I can remember-starts looking at me like I'm more than just Jay's little sister, everything changes. What started with stolen glances and secret kisses quickly spirals into something we can't control. We try to hide it. Lie about it. Protect Jay from the truth. But some secrets don't stay hidden forever. Now, Heeseung and I are risking everything-his friendship, my family, and the heart I swore I wouldn't hand over. Love was never the plan. But neither was falling for the one person I should've stayed away from. #3 on #JAYPARK #7 on #JAKESIM
