Formed in 2019 after performing live accompaniment for the film Haruneko, the two-piece band Bialystocks has been winning support with their distinctive sound design.

Released on January 5, 2026, this track was written as the ending theme for the TV anime A Sign of Affection (Ikoku Nikki), and its warm sound gently lingers alongside the story, making it a soothing listen.

The lyrics delicately depict emotional fluctuations that words alone can’t fully convey, mirroring the frustrating sense of distance felt by the anime’s characters and striking a chord with listeners.

It’s a calming mid-tempo number where a folky melody and refined ensemble gradually build a quiet sense of elation.
