Two twins get isekai’d and have the power to talk telepathically to each other, they get adopted into royalty (or they are royalty? - idk i forgot oops hehe-) anyway it’s been a long time since i read but iirc it was pretty fluffy and cute
Very sad one shot about mentally ill twins and one of them being abused by his mother to the point he couldn’t even go outside. Very sad but good read if ya ignore the incest
