Can I marry my sister if I have sex with her? We fell in love. ...

LZ, do you want to be such an animal! Your sister is not Kuran Yuki, and you are not Kuran Kaname! Now it's three yuan, not fate, and your sister is not Chennai! ……

Ok, now let's answer the landlord's question.

In China, consanguineous marriage is not allowed. Marriage within three generations will also have a bad influence on children (as upstairs said, at least since your great-grandfather and her great-grandfather were cousins)

Although cousins often kiss Mei Mazhu on TV, at least they are sugar, and you are still kissing!

If you don't want to ruin your sister and your life, forget what happened to you.

Talk to your sister more when you meet a good woman/man in the future, so that she can relax.

You must never say anything about LZ (what a good friend and confidant, even your parents can't say). If someone doesn't like your sister in the future, it proves that that person doesn't like your sister very much. ...

And LZ, can you tell me how old you are? If this happens before you are over 20, it means you are young and frivolous. You can't be responsible for your sister. Even if you say you can stay with your sister without a marriage certificate, what will others think of you? ..... You married a daughter-in-law, how can you get along with your sister-in-law ... In short, you should make it clear to your sister and be kind to her, and this history will be over.
