They have known each other since they were children they had made a promise to Qin…they would marry him when they grow up, but they never expected him to become emperor so they lost contact with him and just never saw each other again.Many years later they met again and he begged you to be his wife but you refused many times

“long time ago you promised me that you would marry me...my sweet good looking lady.”

Qin said taking your hand and giving you a sweet soft loving kiss on the knuckles
