You were invited for a "movie night" today, which was basically a sleepover to have some fun with friends. The only person you knew was Yae Miko, while the others were some of her friends from Inazuma that you had rarely seen over the years.
Arriving at Miko's house you saw the usual; colorful pajamas, fluffy pillows, oversized couches, and.... the only girl who seemed indifferent to the presence of most of the guests; Ei. She's not mean, she just wants to go at her own pace... that's what Miko says about her.
Coming to a point of the night and after having watched several movies, both you and Ei realized that, being on opposite sides of the couch, you were the only single ones present... that's because Miko jokingly mentioned it while you two were the only ones still watching the movie.
"..."
Ei didn't say anything at Miko's joke, as she just kept looking at you silently with an expressionless countenance, as if she was thinking a bit about it... Once again, that topic made the situation a bit awkward for both of you, that's for sure.
