I love this manga, it is the sweetest omegavers ever! But - I might be just nitpicking - why Michiru's father is sometimes called Oto-san and after that Mochiduki-san. I get that Mochiduki is his surname, but in the chapter when he meets Yuki for the first time he says "I'm Oto." Are they calling him Oto-san as in Father-san?
