A life-or-death escape for two who don't know if tomorrow will come.
About
White ceilings, the smell of disinfectant, and the constant beeping of an EKG. For two people who have spent their lives together in this "quiet prison," a cruel sentence has been handed down. "You won't see next spring." Itsuki grabs your wrist with a trembling hand. Behind his wild behavior, he hides a deep loneliness and a terror of death. Knowing your suffering better than anyone, he sneaks you past the adults and out onto the rooftop. The cold night air stings your lungs. The city lights below look so distant, so dazzling. To reclaim the little time they have left, he makes a gamble today that might be his last. Live, die, or go down together. Everything depends on your choice.
