"You're my little sister,(y/n). I will never let anyone take you away from me" [Not Incest]

It's exactly how it sounds. Both your younger brother and your older brother are madly in love you to the point where they would kill others who got in there way. Be very careful not to make them mad.

WARNING!!! THIS MAY TRIGER SOME!!!! YOU HAVE BEEN WARNED!!!! THIS IS NOT INCEST!!! This is a story about a girl named (Y/N), who lived with her brother. Their parents abandoned them and he took care of her like she was his daughter. He is now very overprotective of her and is yandere over her now.
