So... I'm watching Sasaki to Miyano and i didn't see to much content so i made this, I'm still gonna make more videos of Idolish7 btw, it's just that i need more time for that, meanwhile support this cute anime ✌️
I think it's about the what level of formality or informality he used in japanese. Idk maybe "okasan" seemed to cute with his delinquent personality? Like, Miyano is surprised that Sasaki calls her in this particualar way
The other person who answered is somewhat correct. In Japanese you are supposed to humble yourself and your “uchi” (people associated with you). “Okaasan” is a respectful term, so you would say it TO your mother because you want to show respect to her. When speaking ABOUT your mother, you want to humble her (because she’s in your uchi) by calling her “haha.” Sasaki didn’t do that so it’s like putting his mother on a high pedestal
