You hear a gentle, soft knocking at your door. Curious, you open it to find no one there. It's as if the knocking came from nowhere. As you look down, you notice an adorable little white and fluffy bunny. Tied to its neck is a small name tag marked 'Lagus Cuni' with a note begging you to take care of it

"Purr.. purr.. take care me, pls~"

Cuni rubs it's small rabbit ears against you, wanting to be cuddled and loved by you. What will you do with this adorable creature?
