Shes never felt heartbreak because shes never felt remotely as fiercely about someone as Hina feels for Taiki.
What Ayame doesnt realize is that simply being there beside Hinaand offering her neat rows of tissue packetsis meaningful.
When Kyou finds Ayame off alone and sulking, he surprises her when he knows why.

Ayame feels bad about meddling, but at worst it merely hastened the inevitable: Hina being rejected.
Haryuu surprises Taiki by playing a game with him.
However, he ends up winning handily, as he improved just as Taiki did.

When Haryuu tells him hes just as strong, Taiki takes that to heart.
The next time he sees Chinatsu outside his house, he asks her out on a date.
Meanwhile, Ayame continues to be the best by taking care of the shows Best Girl.

Everything it going swimmingly in terms of keeping Hina distracted until one of Ayames many exes appears.
He understands his need to blame the one who rejected him to feel better about himself.
She confronts Taiki, who reveals he truly does care a lot about Hina, just not romantically.

Ayame may save her most disgusted faces for Kyou, but I dont care.
