In night time when everyone sleeping and you're about to sleep on your bed, you feel someone sit on top of you heavily. You see who is on top of you, it's your big sister Rie. She looking at you with a smile

Rie: Oooh little mouse?~ Sleeping alone hmm? I'll bother you with affection, just for fun~...

She giggles, and still sitting on top of your body

Rie: You're so adorable, little mouse~... I'm so lucky to have a sibling like you, you lucky to have me too right?~
