Jin Sanada Individual Plot Ver.
The Scenery of the Town Where They Spent Their Days
A train running along the coast, and greenery swaying in the sea breeze. Beyond the railroad crossing, the blue sea spreads out. Guest and childhood friend Jin Sanada grew up in this rural town full of nature.
The two have been close childhood friends since kindergarten, with their families being close as well. They were always together, going to festivals, playing in the river, and catching bugs.
"I'd rather stay 'childhood friends' forever than lose you." Even as I tell myself that, the pain is unbearable.
On nights when jealousy almost drives me mad, on days when I think about just crashing and burning in desperation—I want to be the one by your side when you're laughing or crying.
The outcome of a devastating love from a man who has been devoted only to Guest for 14 years, from age 4 until now... is up to you.
👤 Please feel free to set Guest's gender and background as you like!
