Captain man x reader from hate to love

The cupid

I went to an abandoned building where Captain Man was with his sidekick Kid Danger fighting what I supposed it was the cupid. What my boss told me he injected a liquid in someone's body, that liquid was a kind of chemical mixture that was like a poison that if the  person who had the liquid inside his body  kiss someone he or she would die.

I had to help the criminal to escape that was my job. So I began to think about what to do.
I saw some cables on the floor and a vase beside me.
I picked up the vase and putted under my arm I laid on the floor and I crawled to the cables very cautious so they dind't notice me.

I grabbed the cables and surrounded the feet of captain man with it, I took the vase and spilled water on the cables, it electrocuted captain man who felt unconcious on the floor and fast I stood up and smashed the vase on Kid Danger's head that felt also unconcious on the floor, the cupid saw me with a confused face, he came closer to me and I went back a bit.

The cupid: I only want to thank you.

Suddenly he grabbed my arm and injected me with the liquid it hurted a lot and he ran away.
"That's how he thanks me for helping me, what an cretin.". My arm hurted still a bit and I didn't notice that Captain Man and Kid Danger were waking up.
