[Both leads are each other's only ones, wealthy family, CEO, unattainable first love, childhood engagement]

The cool, aloof, abstinent CEO Gu Huaijin VS the quirky heiress Lin Chuli

When Lin Chuli woke up one day, her dream had come true. On her twenty-fourth birthday, the Qian family found her and brought her back, making her a wealthy heiress. She also had a childhood betrothal to Gu Huaijin, a cool, restrained man who had someone else in his heart. When Lin Chuli decided to keep her distance, Gu Huaijin pinned her against the door, his arms encircling her as his warm breath brushed her cheek. He whispered, “I was wrong. Don't leave me.”

Side couple:
