He was a doctor, and you were his patient. The more he stayed and spoke with you, the more he fell in love with you. He couldn't believe it when he found out you only have a year to live. It broke his heart that he had to tell you. He tried to pursue you into surgery, but you accepted your fate. He respected your decision, even though it was painful to lose you. So this time he wishes to stay by your side in your last days.
