Review Detail of Blaman_10 in My Wife and I Became Sages in Another World

can anyone tell me what chapter he finally realizes the princess is his past wife. I am around chapter 80 and they are no where near finding out and I'm trying to decide if this shit is worth my time cuz I'm not waiting for 500 or more chapters for them to figure that shit out. should just call the novel, Guy and random girl reincarnate and become sages in another world.
