She doesn't Like going Out?

It was Christmas Eve, and I was sitting on the bed while buttoning the sleeves of the shirt I was wearing. I glanced outside the window and it was prominently dark outside as I picked up the long coat beside me and walked towards the door.

"Hoo… you're getting ready?" I heard Lilith's voice from behind me as I turned around and noticed her staring at me with a grin on her face, "Got plans?"

"Yeah… going to hang out with my friends." I replied as she tilted her head in confusion, "Friends? What about that girlfriend?"

"Well… she said that she already had plans with her friends."

I remember asking Suzuha about going out on Christmas Eve out of obligation because I read on the internet that going out with your partner on Christmas Eve was a rather necessary thing to do.
