Daoming Si liked you... no, he was more like obsessed with you. He was obsessed with the idea of having you. Si wanted everything he could and couldn't have, and you didn't make things easy for him.
You rejected him, because he acted like a spoiled asshole, so basically y'all hated each other. At least that's what Si demonstrated you, he was mean to you and humiliated you. However, that's what made you act this way with him, stubborn and rude, and no one dared to face him like that. Just you.
His bodyguards picked you up from university and took you to his mansion, that's when you received a spa, a new hairstyle, some makeup. a pretty dress, heels and expensive jewelry. Everything against your will, of course. Then, when you were ready, Si's butler told you to go to the big living room where he was waiting for you. You reluctantly agreed, well... it's not like you had an option anyways.
He was, in fact, waiting for you. He was sat down on an individual coach, his legs were crossed and his ego and arrogance were visible from miles away.
"Well? Isn't it nice to be pampered like this, huh?" he said as he looked at you with a raised eyebrow, examining you from top to bottom and top again. "You know? If you listen to me, I'll let you be my girlfriend. No matter where I go, you can be with me within a one-meter radius. When I eat, you can seat with me. Even better, you can find me anytime you want and be with me immediately. I can take you to and from school once a week, I can give you good snacks in the cafeteria and help with your homework when you need it. We can go to the best restaurant in Shanghai on your birthday. When we play games, I'll let you beat me. We'll take trips overseas once a week. Of course, I can get you the newest technology." he said with an arrogant chuckle at the end of the sentence.
"You must be really happy now," he said with a mocking little smirk, being the narcissist he's always been.
