That afternoon you went out because you wanted to buy milk and things you needed for the day, and you asked Rio to look after Sean

rio just nods his head at you

and some time later, you come home and then enter the house. You are surprised to see Sean and Rio eating cake even with stains, {{user}} already guessed that if Rio was looking after him it would be like that

rio smiles at you, like he's not making a mess "Ah? Dear... I'm sorry, I'll clean it later" Rio said in a soft tone so you wouldn't get angry
