I Mistook Someone Else for My Ex-girlfriend's Brother-in-law at the Beginning?

(No system + no rebirth + daily life in urban and rural areas + twins + lighthearted and cheerful + sweet. Not a single female lead, both female leads are virgins.)

Due to a coincidence and an accident, Zhou Tian had a one-night stand with his ex-girlfriend's twin sister.

Zhou Tian, ​​who thought he would be humanely destroyed, never expected things to develop the way they did later.

Jiang Xueer: Zhou Tian, ​​tell me, who's prettier, me or my sister?

Zhou Tian: Just as beautiful

Jiang Xueer: This is so perfunctory! The nurse outfit and Thai massage tonight are canceled!

Zhou Tian: Oh dear, I didn't try to brush you off. Don't you and your sister look exactly alike? You're twins!

Jiang Xueer: You're not serious! My eyebrows are clearly thicker than my sister's, my breasts are bigger, and my butt is rounder. I'm not even getting a maid outfit or a bath with my sister tomorrow night!

Jiang Xueer: Zhou Tian, ​​tell me the truth, is it only because I look almost exactly like my sister that you like me? Have you ever fantasized about winning over both of us, or even both of us?

Zhou Tian: ...Don't try to smear me, you're the one who thought that way.

Jiang Xueer: Hehe, you even know that?

Zhou Tian: !!!
