Love even in sickness

You entered the room with bundled sheets in your arms. The sliding door remained open in hopes of letting the cold air of the room circulate with the warm air of the hall. However, the heater couldn't hope to compete with Shouto's power.
Ever since you laid him down, his quirk had been going haywire. One minute your lover would be scorching hot and the next freezing cold. It was taking all your remaining resources to keep up with the sudden changes.
"I found another futon."
You frowned as you looked down at his face. Ice had started to cover him once again, and you quickly worked to switch out the chilled blankets with ones out the dryer. You never been thankful to still have electricity. The house had held up pretty well despite the chaos over the past few weeks. When quirks first appeared in the birth of a bioluminescent baby, everyone wondered how far humanity could evolve. No one really thought of how it would end or expected a simple virus that made people with quirks deranged and highly aggressive would be the calling card for the end of super powered humans.
You had to watch your friends fight each other with relentless attacks, and Shouto had protected you and been by your side. Now, you were trying to stay by his side and make him comfortable as possible before he too fell into the same sickness as the rest of his former classmates.
You heard him cough, and a frown pulled at your lips at the fitful, choked gasps. It wouldn't be good to give him more cough syrup right now, so you tucked him in tighter and were greeted with half-lidded blue-gray eyes.
Shouto sighed gently, white air blowing from his lips as he mumbled, "Thank you, Fuyumi."
You stared at him, and your brows furrowed with worry. "Shouto, it's not Fuyumi. I'm (Name)," you told him. His eyes clouded with uneasiness, and your heart twisted when you noticed the pure confusion on his face. Each lapse of his memory reminded you how little time you had left. You kneeled down to his side, grasping his hand with your own. You grazed your thumb over the golden band around his ring finger, almost identical to your own. "See, we're married, remember?"
Then, there's a vague sense of familiarity in his eyes. He shook his head, regaining his composure before addressing you again. "Right, I knew that...I'm sorry, love."
"Don't worry about it," you said and sat down next to him. "How are you feeling?"
"A little better now," he reassured you, color returning to his face, and you smiled and leaned your head over his own.
You smiled. "What do you want to do today?"
"Anything is fine," he answered.
"I asked what you wanted," you repeated. You couldn't accept just anything. You wanted to do the things he liked and enjoy it with him while you still had the chance. He blinked at you before slowly sitting up and facing you with a slight grin. An arm went around you and pulled you into his chest.
"Come here."
You listened to his heartbeat, a little slower today then yesterday, but it still had the same effect of making your own pick up as his lips pressed to the top of your head. You laid back in the futon, cradled to him. You noticed the first inklings of warmth coming back to him as you place your arm around his waist, and you hoped that maybe some of your own could seep into him.
"This kind of reminds me of our first date." The first time you went out together, the carnival had come to Musutafu. The two of you had gotten stuck on top of the Ferris wheel, and Shouto had let you cuddle against him the entire time so you wouldn't get cold. You brushed his hair from his face and began to flake off the remains of slowly melting ice. "Though, I get to make sure you stay warm this time."
"I always feel warm with you," he whispered, holding onto you tighter and nuzzling your body close. "I love you," he proclaimed with a whisper.
"I love you, too," you returned, adding another soft kiss to his lips. When his lips quivered against yours, you feared this might be the last memory you had while he was scared of who would protect you from now on. You decided now to stay with him, and not move. You regretted not doing much but when hours later you finally gave into much needed sleep.
You woke up to the crashing of glass from a distance. The sound startled you to a sitting position, and you were afraid someone broke in. When your shifted, your heart sunk when you didn't see Shouto by your side. Another clashing of glass made you jump, and you hurried to your feet and made your way to the kitchen.
You froze at the entrance and stared at the hunched over form of your husband. His hand was drawn to his left eye, and it almost sounded like he was sobbing.
"Shouto?" You hesitantly made your way over to his side, dodging the piles of broken glass.
He hoarsely spoke, his voice dragging and cracking between pitches of low and high. His voice was too low and distracted to be speaking to you directly. "What are you saying? Why would you say that?"
"Shouto, what's wrong?" you asked, gently placing your hand on his shoulder and pulling him. "Hey, look at me," you whispered softly but you wish you hadn't when he looked at you with dark eyes. It was a cold gaze that made you whimper and step back from him. Though, it was the heat from his body that made you hold up your arm in self-defense as the first arc of flames shot out with the swing of his arm.
"It's all your fault! You made her hurt me."
You collapsed into the edge of the dining table, the wooden pillars screeching on the floor. Your eyes widen with the heavy steps of him walking towards you. The crackling off flames on his left side highlighted your frightened face with orange flickering light. Realizing your situation, you frantically kicked yourself under the table.
The furniture was easily flipped over, clambering behind you with a thud that makes your ears ring. You dodged to the right in time to avoid a spike of ice from his foot, and you stumbled back against the fridge.
"Shouto, stop! It's me!" you screamed, but it was like trying to talk to a robot, one that is determined burning you tho. You turn to run. The first step you take had glass which stabs you between the balls of your foot and painfully cuts down to your heel. You cried out, grabbing your foot and the blood poured out from your wound and spurted on the floor. That was the least of your worries as you were shoved back, the side your head banging against the wall, and you fell with a yelp. You inhaled frantically. Your heart felt like it might burst from adrenaline, fear, and disbelief all at once as fire appeared in his palm.
"Shouto, don't, this isn't you." Instinctively, you curled into yourself to make as small a target as possible. Tears streaming down your face, you buried your head behind your arms. "Please, Shouto, y-you're scaring me."
Then just as you thought it would all come down on your in an ending of flames and heat, it all stopped. Hesitantly, you dropped your arms and met his gaze, widened and his body shaking as his bi-colored eyes scanned over your bloodied and trembling form. "(N-name?) Wh-what?"
Shouto exhaled heavily. His gaze left yours and studied the chaos left strewn across the room before falling to his hand still steaming with the release of his quirk. You sniffed, drawing his attention back to you. Both of your eyes full of fear and shock. "I-I am so s-sorry!"
Out of the two of you, you'd say he was more afraid; and when he turned and runs away from you, you knew you were never going to see him again.
