When a gentle childhood sweetheart meets a domineering second generation, where should the weak Su Mu go? Lin Fan and Su Mu were childhood sweethearts who had known each other since they were children. When Lin Fan was about to confess his love to Su Mu, something unexpected happened. In desperation, Su Mu could only ask the nearest luxury car for help. The only request of the owner of the car for asking for help was that Su Mu should be his girlfriend, and Su Mu could only agree. How should Su Mu choose when they meet again ten years later? They are childhood sweethearts who know each other? Or the overbearing boyfriend who shows up halfway?
