Kawaii waifu's manga / #One night stand(5)

I wish the brother was nicer to the sister (fl) but whatever. The couple is quite cute and strong female lead

ML's hella damaged but falls in love w a girl he married because one night they meet at a bar and have sex and find out they're sexually compatible (like double digits per night). Cute couple,, and it actually takes you (somewhat) through the journey of pregnancy and birth which i really like cause i can barely find any mangas/stories where they include pregnancy and the process of it

It's like positively yours and the runway clashed together ,, so cute !!
