A few days passed, Bakugou mainly waking up to eat and drink, Kirishima spent all of it at Katuski's side, pampering him with kisses and licks for hours and making sure he ate every day.
When the week had finally passed, Bakugou was back to work, he looked tired as shit but was steadily recovering with his protective Merman at his side always. When it was Bakugous turn to feed or take notes on some of the facilities fish, Kirishima would find a way into the enclosure and watch his mate work. That fish fuck thought he was being sneaky but Bakugou always saw him hidden behind the rocks, he was too big to hide anyway.
Eventually, Aizawa got sick of it and made Kirishima stay in his tank at Bakugous apartment until he got back home, Kirishima hated it but it was worth the wait when his angry blonde returned to give him cuddles and complain about his coworkers.
After a month, Katsuki was back at 100%, he was still complaining his ass hurt but the bags under his eyes had faded and his skin was back to the normal clear shade. Mina was begging him to come around her apartment and dish about the week he spent with Kiri but Bakugou was reluctant to even speak to most people now, mainly because his heat was coming up but mostly because he hadn't shifted in a while and his bond with Kirishima was making it hard not to, his omegan instincts wanted him to shift, take Kirishima underwater and ride the soul out of him.
But his work made it hard to focus on one thing, he was juggling his emotions to his dumb fish mate, his work and his instincts.
There was also the problem that not once did Kirishima use a condom while they had sex... it might not be a problem because he didn't shift at all but it could be because male omegan Mermen were extremely fertile and it might have made him pregnant anyway.
He'd think about it later, for now he wanted to get home. He passed several coworkers who each waved and smiled but were all met with an intense glare, especially stupid Deku who Katuski flipped off and practically growled at.
When he pushed the door open, Ei was already waiting like a love sick puppy at the door, enclosing the blonde in a bone-crushing hug that immediately sweetened his sour mood:
"Kaaatsukiiiiiiii, I missed youuuu" His Mermans warm voice whispered in his ear and sent shivers down his spine.
"Whatever..." He replied.
Bakugou walked to the kitchen, pulling out a microwaveable dinner and pinching the bridge of his nose.
"Hey, Ei... would you mind going with me to the ocean for a little while?"
That seemed to gain the redhead's attention and make his ears perk a little. "Yeah anything for you Kat, why though?"
At that, Katsuki stiffened and coughed lightly
"No reason, just want to."
That seemed to be enough for the Merman, he turned and sighed, happy that he would go out today.
