I don't think he had a choice; her husband would have died either way as the crown prince looking for them
Think of it from his aspect. His younger, very noble sister with a bright future got "deceived" by a poor commoner, ran away from home, got knocked up as a teen and had a child. Whilst being on the radar of the crown prince and the country.
Yeah but the brother doesn't know she's returning to the past and restarting life. Think of it more like an alternate universe instead of the past life, she's been in 2 different timeliness so far and is living a 3rd one. Nobody knows about the other 2 but her.
You're right and I agree
I have to reread this but didnt her brother kill her husband in her 2nd life?? I coud never hold that mans hand and its ruining the last chapters for me. I respect her maturity though
