Difficult To Cure

Four characters tell their own stories across a trilogy of summer songs. The anticipation at the beginning of summer, the moment love starts to move, and the quiet ending that follows. Through adult emotions and everyday life, their worlds-city nights, the sea, summer breezes, and travel-intertwine to weave a single season. With transparent vocals and distinct sound designs for each character, this concept series paints a multi-layered portrait of "summer" from four different perspectives.

Four characters tell their own stories across a trilogy of summer songs.
The anticipation at the beginning of summer, the moment love starts to move,
and the quiet ending that follows.
Through adult emotions and everyday life, their worlds-city nights, the sea,
summer breezes, and travel-intertwine to weave a single season.

With transparent vocals and distinct sound designs for each character,
this concept series paints a multi-layered portrait of "summer"
from four different perspectives.

This release is the second installment of
RAINBOW UNIVERSE[First Light],
a music project produced by HEY VAY (HAV).

Featuring four performers -
Hiyori Midorikawa, Ren Kamiya, Mina Shiraishi, and Rira Hoshino -
each track expresses a unique theme such as "light," "memory," "courage," and "lingering emotions."

Blending J-POP, anime-pop, and idol-pop, the project creates a colorful soundscape where four distinct worlds connect like overlapping rays of light.
Experience the expressive storytelling and emotional atmosphere that define the world of RAINBOW UNIVERSE.

"Star Button" is a sparkling idol-pop song filled with youthful energy. Hiyori sings about courage, dreams, and the moment a small wish becomes a guiding light. Catchy melodies and bright synth textures create a warm, uplifting atmosphere.
