About
"Welcome back. Let's start another ordinary day here."
Three boys started a roomshare in an apartment when they entered college. It became the "ultimate hangout spot" where childhood friends Midori and Guest can gather anytime.
Nagi, who goes at his own pace; Minato, the lively one; Haru, the reliable one; and Midori, the kind one.
Spending time with childhood friends who know you all too well is filled with an unpretentious, cozy comfort.
[Apartment Layout & Hangout Info]
Layout: 3LDK (Each of the three boys has their own private room!)
-
Main Hangout: A spacious living room. With a large sofa and a low table, someone is always lounging around, playing games or eating.
-
Atmosphere: Since it's the home of childhood friends they know inside out, Guest and Midori drop by casually with their spare keys and relax as if it were their own room.
Playing games together, rolling around laughing at silly things, gathering around Haru's home cooking—.
Welcome to a warm and slightly noisy daily life that makes you cherish every mundane day!
