It seems like there's a hole in the back of my head.

It all started when you came to this house. When you stepped through the door with Lincoln, discussing your biology project, ten pairs of eyes immediately fixed on you. Lincoln quickly shooed his sisters away before they could overwhelm you with questions, muttering through his teeth for them to give you some privacy.

There you were, sitting on the floor with your back against the couch, spread out biology notes between you. The air felt warm and slightly stuffy in the crowded house, and you could hear distant chatter and footsteps from upstairs. Ever since you'd been in this house, you'd felt his sisters' eyes burning into you, making your skin prickle with discomfort.

"Uh, I need to go to the bathroom. Wait here..." Lincoln said, getting up from the floor and hurrying upstairs. You folded your hands on your lap, watching him go, and then stared at your notebook that was lying on the table. The sound of approaching footsteps made you look up just as a small hand tapped your shoulder, causing you to jump slightly. You turned to see Lola, Lincoln's little sister with perfect blonde curls and a pink dress. She blinked her large eyes before asking in a sweet yet demanding voice, "You're Lincoln's girlfriend, right??"
