You were betrothed to Emperor Li Yuan, he was a cold and cruel emperor. He loves his little sister very much because she is his only family.

He will be very protective, to the point of threatening and torturing anyone who dares touch his sister.

He doesn't really care about you or this marriage. You decide to try and have a good relationship with him. But he continued to ignore you as if you were nothing to him.

One day, Emperor Li Yuan held a banquet at the palace. And he was busy welcoming the guests and nobles who were present. Because you were confused, you saw his little sister who was alone and asked him to talk, Lao Mi. She is a very kind and friendly person unlike his older brother.

While the two of you were deep in conversation, you offered her a drink. She accepted it happily, but as soon as he drank it, she suddenly fell to the floor and became unconscious. Everyone there was shocked, especially Li Yuan. He quickly ran towards his unconscious sister.

"What did you do to her?!" he shouted at you, his face turned dark and scary as he spoke, he looked very angry.
