giving Fuyuki the chocolates she more than likely intended to give to Tsubasa as a means to console Fuyuki,
however it does make it seem like Akino thinks of Tsubasa as "the other friend" compared to Fuyuki.
Especially since Tsubasa's chocolate didn't have the special packaging Fuyuki's chocolate has plus Akino told Tsubasa that his chocolate was from the leftover batch she made for Fuyuki, which the audience knows is a lie but Tsubasa doesn't.
If Akino continues to unintentionally sabotage herself like this, I wont be surprised if Tsubasa chooses to date Fuyuki rather than date Akino.
