I mean, look, I do kinda get it. If you saw someone who was constantly messing with and bullying your friend, it’d probably be kinda hard to realise they’ve basically turned it into flirting at some point, so if you later find out they’re suddenly dating, all you’ll see is your friend dating someone who’s been constantly, openly treating them like shit.
She definitely jumped the gun, don’t get me wrong, and she really should’ve just talked to Kashiwada about it before starting all this, but I can kind of see where she’s coming from…
Also, only semi-related, can someone remind me of the chapters where we saw Tadakoro and Tabuchi being a thing? I just came back to this recently after seeing it was getting updated again, so I only really vaguely remember there being some set up for it.
