are there any stories where the mc is a protective older brother to a younger sister or he's the younger brother and the older sister is protective of him. i'd like it if he had a harem and the sister was in it. when i mention a harem i don't technically mean an anime harem where the mc is oblivious to everyone's feelings and things but one where everyone is upfront with how their feelings and how they want the relationship to work. I'd also like if there was an extra sister. maybe an extra older protective on or an exstra younger one to be protected.
