wow, i dont think ive been more disappointed in a manga in a while. gorgeous art and cover drew me in and the ml being a dilf piqued my interest, but things went downhill very quickly and very tragically. legrand is basically just a child predator and groomer, who ended up getting to marry his victim and impregnating him. didnt feel like love between 'mates' at all, instead just felt like a weird obsession.
