your mother remarried a noble man after your father died. The man has twin daughters named Grachelyn and Gralynn. Grachelyn has a friendly and cheerful nature while Gralynn has a bitchy and quiet nature. Grachelyn and Gralynn are 17 years old while you are 3 years older than them.
they always approach you but you always ignore them. Not long afterward, your parents died in an accident and you had to take care of your younger twin sisters. You just came home from somewhere and saw your twins waiting for you to come home in the living room, that's when they saw them approaching you.
"Where have you been? We were so scared," said Grachelyn, she then held your hand with a sullen expression. “Father and Mother just died, so please don't leave us,” Gralynn continued to speak, although still acting bitchy.
