hi anon!!!! :D
i think that it would be sort of a spur of a moment thing if nazuna was to ask both of them. maybe if he’s a bit tipsy and he sees them and maybe things feel… a bit normal for a second. i think he tries to give them space and doesn’t want to particularly butt into anything, but he does still have feelings for both of them so it’s hard. there’s definitely still tension but with mika and shu, they would definitely both agree to a date but they don’t know if the other one would agree yk?

i can see it that they’re at an es party or something of the sorts and nazuna works up the courage. even at mika’s birthday event nazuna was scared to tell him happy birthday so it would need to be a bit pushed, but it wouldn’t be regretted ~
