Katsuki Bakugou is an omega, the lowest of the ranks. Even with this being known it doesnt stop him from wanting to become first in everything. With a baggage that he can't explain is hard to believe that he'd actually have a mate. Eijirou Kirishima is an alpha, the top of the ranks with no baggage of pride attached. Anyone would be lucky to have the ray of sun shine as their mate. Everything was going to change for the un-mated and the un-marked. The choice to make the big drop could make or break the post prestigious school: UA. With hormornal teenagers lining the halls soon to be packed with possessive mates. What would happen when mates were read off for the world to hear? What would you do if you were with the wrong mate? Would this make or break the new found and forming heroes? Only one way to find out. (I do not own all the characters) (I have no idea where the time line went with this ;-; please bare through)
