It's sorta confusing but it stems from last chapter with manager-san hiding how severe her sickness is. Maybe her not being truthful to someone she's close to and maron having to fish for the "i miss you" is why she's calling her a liar? idk
yaowza, didn't think we'd be getting into it so soon with the misunderstanding(?), doubt the story will let Naoi explain so soon so we just gotta bear the angst for a bit.
I didn't watch MyGo at first, but now I did and this kinda makes sense. Taki loves Tomori (canonically as well), but it seems Tomori is dating Anon in the doujin, so she's depresso and takes advantage of Raana having thought she was Tomori (Raana seems to have feelings for Taki).
Anyway good doujin
