It's kind of amazing that it's been 2 1/2 chapters and we're still on this one night where nothing was going to happen. Admittedly, things are moving a little slower than I'd have liked. So, Mayu asks him about the reason for his breakup and he ends up not telling her. Would he talk to Ayaka about it then (assuming he hadn't already and I just forgot...)?
Also, is this chapter telling me Ayaka has a chance? In a manga where Mayu is the titular kouhai and her likeness is plastered all over the covers of this, front and center? Please, I want to believe but the signs are just stacked against her. As his old friend from HS, she's the closest thing to a childhood friend in this story, and we know the trope about childhood friends and romcoms...
