Zhongli was going to leave..he didn't tell you that he would be going to another country to study there because he knows it will hurt you

He's been with you since childhood, he secretly had feelings for you ever since and he promised not to be inlove with someone else

After two years Zhongli finally came back..you were excited to see him, but what shocked you was he came back with a woman and a child..

Everything was just a history and you were just enchanted to meet him
