A/N: this piece is set during their third year, also I tried to make it as fluffy as possible.
With a hoarse voice, under the blankets
Todoroki didn't get sick often, so when he does its only natural for Izuku to fret over him and drag him to bed. However, this time there was the additional worry and fear since his flu was caused by a villain's quirk.
"We' not risking it" Midoriya argued as he took Shouto to recovery girl, hand in hand the whole way to U.A, earning stares and whispers, some photos that would surely piss of Endeavor.
"There is nothing to be worried about, just some rest and he'll be good to go" Recovery girl informed, "rest up".
"See everything is-" Shouto sneezed mid-argument, freezing the tips of Midoriya's hair, "fine"
"Shoucchan, did you hear your voice, and you barely have control over your quirk" hero Deku argued as he pushed his partner towards the bed, recovery girl long gone and no where within sight.
"Sleep next to me as well" the half cold half hot hero complained as he climbed the bed and crawled under the blankets, shoes and combat vest neatly discarded on the side. Torn between what to do, Izuku sighed in defeat at the mere expression Todoroki gave him, who knew that the class' number one hottie could look this child-like with the pout and puppy dog eyes, he'll make sure to remind Todoroki of it every chance he gets.
It didn't take long for Shouto to fall asleep like a rock, obviously Izuku was the one with the problem as the temperature keeps fluctuating from cold to hot, one minute he is freezing under the blankets and another he wants to the throw them away. Soon enough as the temperature flips toned down, he was left to his own thoughts, analyzing quirks and creating counter strategies, thinking of ways to avoid Endeavor since he is sure that the flame hero will make his way to the campus to reprimand his masterpiece for such mistakes and probably whisk him away for another training session, knowing that Shouto would return to school looking worse than ever.
A small nuzzle to his side broke him out of his train of thoughts, smiling Izuku wrapped his arm around Shouto and pulled the blankets even further above them, in fear of letting anyone ruin this delicate moment, "love you Izuku" Shouto whispered, his voice still hoarse and tired, his warm breath against the Izuku's skin.
"Me too, me too" Midoriya whispered in a soft voice that could barely be heard, filled with overflowing emotions, tender with love and admiration.
A/N: I feel like this is a good way to end it. On another note, recovery girl is outside of the infirmary not letting Endeavor get inside and basically she managed to kick him out of the campus.
