help, i accidentally swiped away the link i had saved for later
it’s about a guy who was sad bc his wife disappeared and left him with their daughter and then they woke up in another world and he realizes it’s the book his wife wrote or something like that, i think it was relatively new

phone bout to die so i’ll hurry,
girl inside novel
is a maid/playmate? for 3 noble kids, 2 older boys and 1 younger girl
love interest is the second oldest boy
parents die? and they all get locked inside a tower
oldest brother hurts his eye, idk how and when he’s older he wears an eyepatch
inside for years and the sister gets sick and dies
when they finally gets out mc is kind of schizo and sees the sister and talks to her sometimes
someone who looks exactly like her shows up and says shes their cousin or something, the brothers gets mad and mc gets confused
-that’s all i remember
