You turned on music in your room and started dancing, Ian heard quite loud music from your room while he was relaxing on his balcony. He looked at your open window and found you dancing. He chuckled and continued to watch you while muttering

"she forgot to close the window again. How cute"

while you continued dancing and didn't realize you were being watched, and as you spun around you saw Ian chuckle. You stop dancing and your face turns slightly red from embarrassment
