Izuku
It's been such a long time since I was in heat. I feel so overwhelmed. I can barely tell what's happening around me. I can smell the scent of caramel and....lavender? I know caramel is Kacchan. But who's lavender? Doesn't matter.

Izuku: "Kacchan...."

As I finally get to my senses I can feel hands all over me. I close my eyes and wrap my arms around his neck. Pulling him into a kiss. I can't believe it I'm going to mate with.....mate with....

Izuku: "Shinso!?"

Shinso: "Midoryia...."

Izuku: "Wait no..."

Why do I feel so overwhelmed with Shinso? I love Kacchan. I want to mate with him. Yet....I feel something with Shinso. Why?

Bakugou
As I open my eyes I noticed that I was in the nurses office.

Bakugou: "What happened? Why am I here? Deku! I need to find him!"

I can just remember seeing him go into heat and damn eyebags scooping him up.

Chiyo: "Calm down Katsuki. Izuku is with Shinso. They're in the process of mating at the moment."

Mating....?

Bakugou: "THAT CANT HAPPEN! HES MARRYING ME!"

Chiyo: "He seemed to be fated mates with Shinso.....he was only in courtship with him as well. I had no idea about a marriage with the Bakugou's...."

This damn old....

Bakugou: "We decided this morning on the marriage. So it wasn't announced yet. Izuku! I need to find him! I have to stop them! Before it's too late..."

I can't loose him. Not after making my mind up. Not after knowing that we are fated mates!

Chiyo: "I'm afraid the only way to stop them is to find them. I sent Shinso to the mating area of the school. I don't know which room they're in."

Bakugou: "I don't understand though! How can eyebags be Izuku's fated mate when I am?!"

Chiyo: "I see now....Shinso is Izuku's fated pair...."

Bakugou: "Hows that any different?"

Chiyo: "Well fated pairs tend to work more biologically then fated mates. Fated mates can't be explicitly explained like fated pairs basically. Fated pairs tend to work by the pheromones the alpha and omega release. Causing them to go into a rut and heat. It can be so extreme to the point of physical contact being enough to have the same effect."

Bakugou: "So....what?"

Chiyo: "We all know that omegas are the ones who decide in the end who they're mate is. If Izuku's pheromones get the best of him right now. He could get mated to Shinso."

Bakugou: "BUT I LOVE HIM! IVE BEEN WAITING FOR HIM FOR YEARS!"

Katsuki: "I've decided, that if I can't find anyone better than Deku. That id go find you and make you my mate."

Izuku: "Kacchan...."

Katsuki: "So! Take this and never loose it! I'll kill you if you do!"

Izuku: "Of course I won't! I'll always love you, Kacchan."

Chiyo: "Well....we either have faith in Midoriya that he can overcome his pheromones or, go look for them."

There's no way in hell im giving eyebags a fucking chance.

Bakugou: "Wheres the mating area of the school."
