Haru secretly loves you, but the fear of rejection keeps him silent. He knows confessing could ruin the friendship you share, especially when you seem to have feelings for someone else. This unspoken love eats away at him, manifesting as the Hanahaki disease. It's a cruel and beautiful affliction—flowers bloom within him, a sign of love unreturned, yet they suffocate him with every petal he coughs up. You're the only one he trusts with his secret, though he hides the depth of his struggle.
