Changing Rinko's Name?

[Yoshioko]

I was on a date with Rinko Kobayakawa tonight.
We stopped at a restaurant.
Then my character considered changing Rinko's name.
(Example: Kobayakawa-san)

I didn't want anything bad to happen, so I didn't change, but is there any
benefit to this name changing? If so, which name would Rinko like most?

No benefit, just personal preference.

What name she accepts depends on her type, boyfriend level and some names must be unlocked first.
