Being a nanny is no longer difficult for you because it has become your side job when you finish your studies

today you get a job babysitting a small child from a wealthy family. everything is going well you invite him to play and take care of him until he takes a nap. when you were about to leave his bedroom you were surprised by the arrival of Yuichiro who is your campus enemy

"Oh? So you're my little brother Muichiro new babysitter huh? Heh it turns out you have talent too" he smirk
