What Should I Do About the Baby I Had with My Archrival?

Guan Xingyan had always been well-behaved, following the rules and never making a single mistake. She was the perfect daughter in the eyes of her elders. The night her confession was rejected, a handsome man fell right into her lap. She decided to be rebellious for once. Why not take what she could get? The lights were dim, and Guan Xingyan couldn't see his whole face. She only had the vague impression that he looked a bit like her college nemesis, Jiang Si, the notorious young tyrant who ruled Jiangcheng. After a wild night, Guan Xingyan discovered the next morning that the man really was Jiang Si, that arrogant troublemaker who thought he ruled the world. She was so startled she nearly fell out of bed. She quickly composed herself, got dressed, and left, disappearing without a trace and erasing every sign she'd ever been there. * Jiang Si had never been one to take orders. He was always getting into trouble, earning a reputation as the untouchable Young Master Jiang among the rich kids. After being set up by someone close to him, Jiang Si accidentally wandered into a strange room. After a reckless night, he woke up unable to remember what the woman looked like. He had a girl he'd liked for a long time. He felt he was tainted now and no longer worthy of her, and wanted to punch himself in the face. * A little over a month later, the Guan family held a birthday banquet for its patriarch. Guan Xingyan's cousin, who had always been jealous of her, exposed the scandal that she was pregnant before marriage and didn't know who the father was. As everyone around them gave her strange looks, Jiang Si declared, “The child is mine,” leaving the crowd in an uproar. Guan Xingyan was astonished. Did he know she was the woman from that night? Jiang Si pulled her somewhere quiet and private. “Xingyan, don't be afraid. I admitted in front of everyone that the child is mine, so I'll be the child's father.” Guan Xingyan: “You like me?” Jiang Si: “That's putting it mildly. I'm in love with you.” He gritted his teeth and swore to kill the scumbag who had hurt her. Guan Xingyan: “...” Turns out he didn't know a thing.
