In Fugezuki Town, emotions are the food of the spirits, and the boy who lost his smile healed the cracks in his heart with a cup of special concoction.
In Amamiya Aoi's bandaged left eye, sleeping was the unhatched Elf King. He runs a cafe that looks ordinary but actually uses "emotional drinks" to heal people's hearts - **Caramel Teardrop Latte** melts sadness, **Mint Joy Soda** awakens happiness, and the price of each drink is an item that carries memories for the guests.
Fujiwara Saku, a talented violinist who lost his hearing due to an accident in a concert hall, has a defective piece of music elf hidden in his hearing aid. When he breaks into the cafe and finds golden light seeping out from under Aoi's bandage, the fates of the two begin to intertwine - Saku's music can soothe the berserk spirit, while Aoi's special drink can relieve his tinnitus.
But as "elf rampage incidents" surge, they gradually come into contact with the truth: Thirty years ago, Aoi's mother stole the Elf King from the "Emotional Torrent", causing the barrier to collapse. Nowadays, black marketeers sell emotional drugs, emotionless people hunt elves for revenge, and the ancient contract of the shrine is about to expire...
"If you can't even feel pain, are you still alive?"
When Aoi's bandage completely falls off and Saku's musical fragments spell out the musical score to awaken the Elf King, they must choose——
Should the contract be repaired so that humans lose their emotions forever, or should the Elf King be allowed to wake up and devour the world?
Concept: Even if you lose your emotions, the warmth of humanity still exists
