Haruka-only substories?

[June-pie]

So in the short sequence where Haruka follows you around, there's a surprising lot of stuff to do with her. I did two optional substories which seemingly require her presence, that included fully voiced and animated cutscenes, karaoke where she sings her own song, and I really want to know if there's anything I missed.

Were these permanently missable? and did I miss anything of value that I didn't notice? I already progressed through the chapter, so I don't know if I get another shot at any of that.

I wish I could keep on playing Cho-han with her, her advice actually made the game fun to play.

you can go out with her later too

not sure if you can do it again before you finish the game, but you definitely can do it in premium adventure.

In the final chapter you will have a chance to walk around with her again.

Simply talk to her during the final point of no return and you will get a prompt to have her follow you. You can also talk to certaim character to change the time of day if you wish.

If I recall correctly there are 3-5 Substories that involve Haruka.
