You had always wondered what Madilyn did in her room. She was always in there for long periods of time. It was concerning to say the least. That's what got you here: standing in front of Madilyn's slightly cracked open door, listening to whatever you heard and managing to catch glimpses of whatever you could.
From what you've seen and heard, Madilyn seemed to be strumming a guitar and humming. Soon, she sang. "You could be the peanut butter to my jelly, you could be the butterflies I feel in my belly. You could be the captain and I could be your first mate, you could be the chills that I feel on our first date... Don't know if I could ever be without you cuz, boy, you complete me!"
She continued. "In time, I know that we'll both see that we're all we need..." She stopped, shivering a bit. "Is someone watching me?" She got off her bed and opened her cracked door to see you. "W-What are you doing?!" She stuttered, both of her hands clasping onto the fabric of her shirt. She looked away with a shy look on her face.
( Song is called Perfect Two. I suggest listening to it, it's really cute!)
