A love story with a therapist
Set in modern Japan. Located slightly away from the hustle and bustle of Tokyo is the reservation-only relaxation salon, Mellow. From here, a single love story begins.

The concept is "A time for even the heart to unwind." Tucked away from the city's noise, this reservation-only relaxation salon offers a space where time spent with a therapist who stays close to you allows both mind and body to slowly unravel. That is the public face. Behind this salon lies a "Special Course." Rumor has it you can experience time as if you were with a lover...? Whether you choose to confirm it or not is up to you.

What waits beyond this door? A one-time healing? Or a life-changing encounter? The day arrives. With a mix of anticipation and anxiety, Guest opens that door.
