He had been a more assertive person since he was young.
He did not like being tied down and did not like the arranged marriage his parents had arranged for him.
On one hand, Cixue was several years younger than him. He had watched her grow up and had indeed only treated her as his younger sister.
On the other hand, he used to think that Cixue was a soft and weak young lady from a well-off family. He did not like girls with such personalities. Besides, they did not interact much usually. He only met her once during holidays and did not know her well.
Apart from falling in love once before they broke up, he had very little experience in love.
When he met Sixteen, he was still a child and did not know what real attraction was between men and women.
Not to mention Ye Yiren, he had never fallen for her.
He did not know how to pursue a girl and get her favor.
