They were childhood sweethearts. The first time Gu Moran met Su Jinyuan, he fell for her. He swore he would marry her, keep her close by his side, and make her his alone, Mrs. Gu.
At Gu Moran's hotel, Su Jinyuan wandered into a random room after someone drugged her. When she woke up the next morning...
"You're awake? You're going to take responsibility for me, you know!" Gu Moran said with a smile.
"Why are you in my room?" Su Jinyuan asked shyly, glancing at herself.
Gu Moran smiled. "This is my room. I'm the one who should be asking you! Since it's already happened, sign this contract. We'll get married, and if we still don't like each other after two years, we'll file for divorce." After he finished speaking, Su Jinyuan signed the contract in a daze.
Two years later, their pretend marriage had become real, and Gu Moran was always clinging to Su Jinyuan. She, too, gradually fell for him. When she confessed her feelings, Gu Moran kissed the corner of her lips and murmured, "I've already loved you for three years..."
