In classic yuri commenter fashion, Riri is now trying to sink any potential NTR that threatens her pure OTP.
I'm hoping Riri's tactics to escalate from blackmail as she becomes increasingly desperate.
I also can't wait for Kanoko to discover that Riri is the author of her favorite yuri and the spicy developments that might come from it. I wonder if the book of Runa's poetry will figure into it? Such a fun detail that Kanoko's sabotaging the IRL ship her favorite yuri is based on.
