About Our 5th Game — I Switched With My Busty Coworker!!! -Three Fascinating Days- (Patreon)

Our fifth TSF novel game — a body-swap story set in the world of Tokyo office life.

Takuya is a 23-year-old salaryman: bright, a little careless, and not so secretly captivated by his senior colleague Haruna. Haruna is 28, the ace of the sales department — razor-sharp, effortlessly beautiful, and never hesitates to call out Takuya's mistakes.

After a successful client meeting, they wander into a mysterious old shrine in Shinjuku. Takuya touches a statue on a whim. Everything goes dark.

When he comes to, he's looking at himself from the outside.

Three days. Midnight on the night of the full moon. That's their only chance to switch back.

Story Highlights:

Takuya wakes up inside Haruna's body — and immediately has to figure out how to function with it. The weight, the balance, the way people look at him differently on the street

Haruna conducts a brutally practical tutorial: underwear, getting dressed, how to move in heels, how to manage a commute in that body without incident

Life in Haruna's body comes with things Takuya never anticipated — including what it's like to be on the receiving end of the male gaze

A high-stakes business presentation, a womanizing client, and two people who have to fake being each other while everything is on the line

Three days changes how they see each other — and themselves
