//OK SO I was listening to Free! Illustration Works Vol.2 (audio from wakoaime )and track 6 is Perfect Valentine! It the picture were Gou gives everyone chocolate right?? So (THANK YOU nagisaperopero FOR THE TRANSLATION) this is was happened with Haru.
Nagisa: Eeh? Then, Haru-chan, what kind of chocolates would you like?
Haruka: I want mackerel-flavored chocolate.
Makoto: Haru, that’d hardly be chocolate anymore…
Haruka: Then chocolate-flavored mackerel.
Rin: Would that really be mackerel anymore?
Nagisa: A chocolate-flavored mackerel, huh! Sounds interesting!
Makoto: Geez, you two, leave mackerel alone a little! I know it’s Gou-chan, but I doubt she’d really put mackerel in chocolate!
Haruka: So she wouldn’t…
AND THEN THEY EAT IT AND THIS SHIT HAPPENS!!!
Makoto: And Haru?
Haruka: There’s mackerel.
Makoto, Rin, Rei: Mackerel?!
Haruka: Yes… It tastes like mackerel cooked in salt…
