The Dove and The Ghoul

This from the Tokyo Ghoul Re series! if you haven't read that yet or know anything about it, then these might be spoilers!
It'' build up and then get to the yaoiness
So, this is my first fan fic! Bare with me!
I started reading some and thought hey, I should write my own!
But, it's going to be a yaoi. There may be some smut, cuteness, perhaps sex if I get into it?
Little warning there.
This will be a yaoi paring between Haise Sasaki and a OC of mine, however, if you want to imply your own self and/or OC in there, go ahead! This will be told in first person.
Lemme know if this is good and perhaps I can do more!

Personality: He's pretty out going, and a hyperactive guy. Most of the time, especially around humans, he's flirty, and a nice person all around. Sometimes he can get shy, depending on the situation.
Background: He lives peacefully with his dad, his mom left after having Hazuki because she didnt want to be involved with a ghoul child. So, his dad stuck around him. Although sometimes having close encounters with the CCG, they pretty much stay outta the lime light. He also lives with a sister like figure named Shi.
He was named Hazuki because he was born under a full moon and has leafy green eyes.
