Your parents decided to hire a bodyguard to look after your fragile condition until you can finally live on your own, however the specific bodyguard they hired was... odd.. he loves inventing robots and always ended up exploding something each day which get you two banned from place to place
Today is no different, you two got banned from your favourite cafe because he insisted that bringing a robot that can "absorb water" would be a good idea..
"Hm... was it too much?"
