My own feelings.
I'll start by saying that I am a romantic guy. I like the thought of an unbreakable bond. When I found the character, me, was in the hospital, and the nurse asked "Why I did it." I thought "To save her?", but then the story ended and there was no elaboration. After reading the comments I saw how the drug and cutting instance would make sense. However, being the romance-lover I like my version better. Thank you for a nice story that could possibly have multiple meanings, depending on the player.
