Gyubin drops 'Our Summer' via STUDIO363's SERIES363 project

Gyubin joins SERIES363 with a late-summer single

Our Summer (우리의 여름) arrived September 10, 2026 through STUDIO363's SERIES363. Gyubin wrote the lyrics. Kim Sang-hoon (김상훈), a producer from band W (더블유), and singer-songwriter Rubin (루빈) handled composition and arrangement.

What SERIES363 actually is

SERIES363 pairs audio releases with live video. It exists to spotlight vocalists and singer-songwriters, pulling out new dimensions from whoever steps in. Baek Ah-yeon (백아연), Lovelyz Kei (러블리즈 케이), Lee Woo (이우), CSR (첫사랑), B.A.P's Youngjae (영재), and BVNDIT's Minyoung (브브걸 민영) have all participated.

STUDIO363 described the track as pairing Gyubin's clear vocals with late-summer nostalgia. "We hope it becomes a warm memory-like song that can be taken out and cherished at the end of the passing season," the label said.

Where this lands in Gyubin's catalog

Our Summer follows Really Like You (리얼리 라이크 유) and Satelite (새틀라이트). Self-written lyrics on a seasonal single through a curated vocal project—her arc is pointing somewhere deliberate.
