Oof. A truly sad, heartbreaking, and tragic love story of two people whose paths converged and lives were irrevocably changed by the other. I'm left with a heavy weight in my chest. This is heavy stuff. I shed tears towards the end, which I don't think I've ever done for a manga. I took this on, challenging myself to see if it was as sad as the comments were describing and it is indeed a tragedy. Brace yourself, ye who are faint of heart.
