Your Majesty Nero, Please Mind Your Manners!

PS: This is an alternate-history novel, based in part on real historical events.

My name is Ying Zheng.

I am the First Emperor of Qin.

I'm a two-time transmigrator.

I'm in ancient Rome now.

His Majesty Nero has taken a liking to me and wants me to marry her.

What should I do? I'm waiting for an answer online, hurry!
