I thibk I've fallen in love with the goge reincarnation incest au, the idea of Gojo somehow getting a hold of Geto's soul only to put her in his unborn daughter and then treat that daughter as a wife and possibly naming her after Suguru is amazing. I imagine his wife gets into a freak accident after "Suguru" turns 18, leading to fifty something year old Gojo to marry his only daughter, most people figured that because she looks enough like Suguru, Gojo wanted to marry her, not realizing its actually Suguru even if she doesnt remember her past life. I like to imagine he takes her virginity at around 15, the age they met, and tries to rekindle the flame they had or jog any of her memories even if they never slept together in her first life
