Choices

So a lot of people want me to make my mc a Hikaru Genji plan to Kushina,but to be honest i had another plan but so many asked for it so i will ask your opinion

A) Kushina Leaves to Konoha, like i originally planned and my mc Doesn't meet her again till she's pregnant with Naruto (original)

B) I add her to the Harem and Naruto becomes my Son (but then again he would probably lose Asura's Reincarnation chakra)

And C) Minato's Girlfriend (Ic Uzumaki) is sterile so she ask's Kushina for a In-vitro fertilization and then put in her uterus so she can be a mother (but still is Naruto born)
