Death, the personification of death and the grim reaper, is in love with me, Deadpool! Because she can't have my soul due to me not being able to die. I reciprocate my love for her and so I try to figure out ways for me to lose my healing ability, die and be with my beloved. Thanos, jealous because he understood Death prefered my love over him, (Understood? Yeah right.) cursed me with immortality so we can't be together.
Me and Death met in the following comics.
Deadpool (volume 3) #15 (fantasy)
