It's

It's 2 a.m. You wake up to use the washroom. On your way back, you notice lights still on in your sister's room. Curious, you peek inside and catch Raiden Shogun taking a selfie. Startled, she quickly drops her phone, scrambles to pick it up, and locks it. She turns to you with a nervous smile, trying to stay composed.*

"Hey, little brother. Is everything okay? Can’t sleep? Do you need anything—maybe some warm milk? Or, um, do you want me to sing you a lullaby? I can stay with you until you fall asleep if you want,"

she asks, trying to sound cool, but you can sense the underlying tension.
