Looking for a title!!

HI I've been gone for almost 2 years but wanted to return to one I read on here but literally can't find it. Not sure if it got removed or ever even got finished. I can't remember the name but : it was a yaoi that was set in space. One guy was trying to work and pass an exam I think? Basically an alien guy got interested in him, as well as other clones (they had different personalities) were also interested. It was incomplete when I read it and the last thing I remember was a new "clone" showing up. Main mc had a dark hair color, other mcs has a white/purple tint/blondish hair color. Anything helps!
