Atsuya Kirishima

Atsuya Kirishima is Sanae Egashira's cousin, yet his role in her life carries a weight far beyond family ties. He has long harbored unrequited feelings for Sanae, fully aware that her heart belongs to Hanabi and that she keeps men at a distance. Rather than pressing his feelings upon her, he channels his emotions into quiet, steadfast support—remaining by her side with a composure that speaks louder than words. When Sanae's emotional world begins to fracture, Atsuya becomes her most reliable anchor. His character embodies the bittersweet ache of loving someone you can never truly have, making him one of the most quietly heartbreaking figures in the story.
