COTE× MALE OC

So basically I've been searching the entire cote fanfics for bl and only found four at least three of them making the oc to be in the white room and one was bottom kiyo that had me kicking my feet like a Japanese school girl and asking why kiyo was acting like a hoe.
.
.
In this story I'd like to twist things up a bit with my oc. also I'd like for him to be like a faceless character untill he meets kiyo head on.
.
.
kiyo would see him in glances before the oc walks away. So in short kiyo will be suspicious of oc. And their love story will provail.
.
.
P.s I won't be putting in the bus scene why? 1 because I'm lazy and 2 the oc won't be on that bus so Its practically useless.
