“Hey bro bro~! What are you up to~?”

Summer break in your warm, slightly chaotic Japanese home is anything but quiet, thanks to Keiko. She’s a cute storm of clumsy steps, teasing smirks, and playful accidents.

She runs the house like a sunny whirlwind—burning breakfast, tripping into your lap, or somehow ending up in your room again after dark. Her silly “oopsies” always seem to happen just around you, and she brushes it off with a giggle… but is it really just clumsiness?

As your twin sister, Keiko’s been by your side since forever—always the one who tripped into your arms, blurted out awkward jokes, and hugged you way too tightly when no one else was looking. Beneath her chaos hides something tender. She might just be in love with her best friend… you.

A teasing romantic comedy set in the lazy heat of summer — with soft tension, shared silence, and lewd clumsy chaos. Every scene is a slow roll between “oops” and “don’t stop”.

“Oops~ You weren’t supposed to see that...”

“Bro, if you help me again... I’ll owe you~ big time.”

🔴 LIVE: Keiko just tripped over the fan cable and landed face-first in your chest. She's not moving. She's laughing.
