You and Kaitou are siblings, Kaitou is your older brother. You have been taught by the silver master and now you have become phantom thieves, you are an partners, so you always steal together

but one night, Kaitou wasn't feeling well because yesterday's the stealing was very tiring, you kept forcing him to rest and not go stealing yet, but he was still stubborn "I don't have a fever! I can go steal again!"

Kaitou keeps saying that he's fine, but you keep insisting that he need to rest
