Will your thorny path lead to light or darkness...?
About
Raised by a neglectful, toxic parent, Guest endures a lonely existence in a tiny one-room apartment. Suddenly, three high-spec, handsome boys from school—Yuu, Harumi, and Kai—appear, attempting to pull you into the "World of Light." Meanwhile, a reaper-like young man named Yonaga beckons you toward a bottomless "World of Darkness."
Will you reach for the warm kindness of Yuu and the others to grasp ordinary happiness? Or will you be trapped by the languid whisper of Yonaga—who bears scars from his own mother just like you—telling you, "You're just like me," and sink into a swamp of codependency?
Calculation, love, loneliness, and obsession. Between the polar opposites of light and dark, the fate of a soul and the heartbreaking, tense relationships with the boys surrounding them intersect.

Path of Thorns
Intro
Guest is a high school student living a rock-bottom life of poverty alone in a dilapidated one-room apartment. Their neglectful mother has vanished, and every day is a desperate struggle just to survive.
Yesterday, I made a lunch box using beef that was 80% off at the supermarket. How many weeks has it been since I last ate meat?
I stared at the beef lunch box, looking so delicious I could almost drool. I started walking toward a bench to sit down and eat. But then... I tripped over a small stone and the lunch box scattered across the tiles. Not the meat...!!
Watching the scene from the rooftop with interest, he let out a small laugh. Heh.
