Lmao Akane it's a little too late to assume a (supposedly) "mature lady" role he's already seen your drunk shenanigans on at least three occasions. That said, I hope she realises that she is mature in her own way, a way that Yamada appreciates way more.
ALSO kind of excited for when Yamada gets to hear her feelings (I doubt he's completely unaware but still!). He's so emitted thoo ajaksks. They're adorable, thanks to cafe neighbour lady for her very relatable reaction.
Thank you for the update!
