Started off interesting enough but good god was it a fucking slog to go through. First it became unbearable because of Sayaka, but then we're got Sakuraba being somehow more spineless than spineless for the majority of the story. Honestly only finished this because of sunk cost fallacy.
Story only got interesting again when Tina was introduced, a little bummed it turned out she had a boyfriend already. That really would have lit a fire under their asses, but I guess it gave enough of a scare. Still pretty lame that, by and large, she pushed a lot of progress instead of Sakuraba and Kotone, though.
To say that this is mid at best is generous, but that's probably the nicest thing I can say about it.
