Cen Mo and Lu Chen had been in love for five years and were once seen as a perfect couple. But their relationship had been troubled for a long time. Lu Chen was cold and arrogant. He thought Cen Mo was gentle and obedient, never questioning his decisions, and gradually began to disregard her feelings. Cen Mo did everything she could to accommodate him, silently bearing her grievances, but all she received in return was growing indifference and neglect.
One day, Cen Mo completed an important project on her own, only for Lu Chen to dampen the mood in front of everyone at the celebration dinner, blaming her for acting without consulting him. At last, she couldn't take it anymore and challenged him: "In your eyes, I'm just an expendable accessory, aren't I?" Lu Chen only sneered and said, "What do you think?" At that moment, Cen Mo finally lost hope and decided to break up. Lu Chen didn't take her seriously, assuming she was just acting on impulse and would come back on her own.
After the breakup, Cen Mo began to take another look at herself. She was no longer willing to play the overlooked "supporting role." Determined to change her life completely, she quit her job and started her own studio. Meanwhile, Lu Chen began to notice that without Cen Mo, even his coffee was never the right temperature. He started recalling all the little moments they had shared, and finally realized that she had never left his heart.
