Waaah, thank you so much for playing and leaving such a thoughtful comment!!
I probably shouldn't admit this, but I'm particularly proud of that bit of Itsuki's inner monologue too, so I'm really happy it resonated with you hehe
And yep, you're right! Rika's backstory is closely tied to the whole club idea. I MEAN she's always been a bit bold and weird, but... I'll avoid spoilers though, so I won't say much more 😶
