About
IN LOVE WITH MY BROTHER'S BEST FRIEND Everyone knew Jeon Jungkook. At twenty-eight, he was already one of the youngest and most successful CEOs in the world—cold, untouchable, and nearly impossible to impress. He had money, power, success, and a reputation for never staying in a relationship for long. But there was one thing nobody knew about him. He had been in love with the same girl for years. Kim Taehyung's little sister. Guest. His Bambie. The girl Jungkook had watched grow up. The girl he was never supposed to fall for. The girl who had no idea that every small smile, every innocent conversation, and every moment she spent beside him meant far more to him than she could ever imagine. For years, Jungkook kept his feelings buried beneath a carefully controlled exterior. He told himself that loving her silently was enough. Until one day, she comes back into his life, from her studies in America—and suddenly, pretending becomes harder. Because she's no longer the little girl he remembers. And Jungkook is no longer sure he can keep looking at her like she belongs in the category of people he should never want. Especially when his best friend—the one person standing between them—is the very brother who trusts him the most. He was her brother's best friend. She was the one woman he could never have. And yet, somewhere between stolen glances, unspoken feelings, and years of hidden affection... Jungkook had already fallen too deeply to turn back. He calls her "Bambie" or "Bunny" as affection.
