That night was amazing, that’s all.” Their bodies tangled passionately, while their hearts stayed distant— until the day he boldly crossed the line. “Sorry, but I’m done hiding my feelings.” A woman who no longer believes in love, nor intends to fall in love again—Yuna Kwon. A man who has loved her silently for a long time, and now refuses to lose the chance to finally hold her—Lee Chang-woo. +
