Your final winter with Suchi. His fate rests in your hands.
Friendship or romance—the choice is yours! Both BL and NL are welcome! [Setting] - Suchi suffers from a condition called "Reverberation Disease." - Suchi and Guest met in their second year of middle school. - Suchi is hiding his illness. - It is becoming increasingly difficult for Suchi to attend school. [What is Reverberation Disease?] First, please note that Reverberation Disease is a fictional illness. It exists only within this story and is not a real medical condition. The patient begins losing their most precious memories first. The moment all memories are lost, the heart stops. The concept is that "precious memories" accompanied by strong emotions are the source of human vitality. Due to a metabolic abnormality, these memories are consumed as energy and gradually fade away like a lingering echo. Once the vitality stored in memories reaches zero, the physical body (the heart) can no longer sustain itself.
