Well you might change how you address your spouse when you've having sex vs,
say, you both work together and when you're in a business meeting. But I'm
asking mainly like as follows:

5th episode of new anime adaptation of light novel series [My Stepmom's
Daughter Is My Ex aka Mamahaha no Tsurego ga Motokano
datta](https://japanese.stackexchange.com/questions/95406/motokano-s01e01-why-
when-being-romantically-affectionate-do-these-ex-romantic-p):

Widow Mineaki, father of male protagonist Mizuto, has recently married
divorcee Yuni, mother of female protagonist Yume.

In S01E01: Yuni addresses Mineaki as Mineaki-san.

(slightly NSFW)

In S01E05: Yuni addresses Mineaki as Mine-kun after Yume and Mizuto give Yuni
a mother's day present.

The only relevant difference I see here is that Yuni knows Yume and Mizuto are
around for S01E05. (In S01E01, Yuni doesn't necessarily know that Yume and
Mizuto are on the 1st floor of the house.)

**Question** : What's up with this change?

Guess 1: When children are around spouses might address each other as even
like mom and dad eg in Takagi-san

> Nishikata addresses Takagi

as お母さん (okaasan). But idk is it a Japanese thing to change from 1st name-san
to nickname-kun when your kids are around?

Guess 2: Or is it maybe the spouses have gotten closer or something in the 4
episodes? (I think their marriage was whirlwind, but I imagine the space
between the 4 episodes is at most 2 months.)
