If I could begin to be
Half of what you think of me(Spiderman thinks highly of Deadpool, he believes in him even though wade doesn't believe in himself)
I could do about anything
I could even learn how to loveWhen I see the way you act
Wondering when I'm coming back( Wade goes on long mercenary trips and leaves peter alone in New York for days, weeks, even months)
I could do about anything
I could even learn how to love like you(Peter has no problems accepting and loving wade, while wade struggles with the concept of someone loving him back)
I always thought I might be bad
Now I'm sure that it's true(He has always doubted himself even with his insanity and seeing peter proves his doubts are right)
'Cause I think you're so good
( He looks up to spiderman)
And I'm nothing like you
Look at you go
I just adore you(And dat ass)
I wish that I knew
What makes you think I'm so special(Peter sees wade for wade not a monster or a killer)
If I could begin to do
Something that does right by you(Wade is trying to be a hero)
I would do about anything
I would even learn how to loveWhen I see the way you look
Shaken by how long it took(Aka how long a mission/job took, how long he was gone, and how happy peter is to see him)
I could do about anything
I could even learn how to love like youLove like you
Love me like you(Wade is learning to appreciate himself and know his worth)
