B-Side (Part 3)

Then there were the noticeable things.

One day, as soon as Kacchan entered their room, he heard Midoriya's sobs in their sleeping quarters.

"Deku?"

Kacchan hurriedly ran towards where he was, only to see Deku curled up into a tiny ball on the floor. The floor was damp with his tears, his eyes were completely red and mucous was dripping all over his nose. Kacchan could guess that he's been crying for a while now.

"Deku! What happened?!"

He didn't answer, instead, he continued wailing in despair. Kacchan wiped Deku's face which was filled with two different kinds of body fluid. God, Deku looked so pitiful. It reminded him of when they were young. All Kacchan could do was take Deku's hand, his large calloused hands. There, he noticed how much it was shaking.

Kacchan helped him sit, pulling him up. "Please tell me what's wrong."

But all Deku did was whisper, "It's the medicine's fault."

"The what?"

"The medicine!" He exclaimed hysterically.

It didn't make sense at that moment, but later on, it did.

***

Once again, he caught Midoriya crying.

Lately, this was a common occurrence in their room. On normal occasions, he would wipe his tears as soon as he sees Kacchan. However, he still continued crying even if he noticed Kacchan's presence, it means something is terribly wrong.

This time, he was holding a couple of test papers, his exam papers, and every one of them was marked with a morbidly low grade.

"Lately, I have trouble memorizing."

"You doing okay in class?"

Deku doesn't answer.

Deku has been forgetting to do minuscule chores as well like unplugging the rice cooker, turning the faucet off, closing the lights when he leaves the room, et cetera.

As a student in the medical field, that's a great disadvantage.

***

"My hands," Deku wailed. "Kacchan, my hands aren't working properly!"

Kacchan noticed it as well, how Deku's hands were shaking, excessively shaking, in their practical exam in anatomy class. It was worse enough to the point Deku had a hard time holding a scalpel when they dissected the cadaver.

"Kacchan, I'm ruining my own life!" He cried.

Apparently, it was just two of the other side effects. Just two, there's a lot more.

***

After repeatedly failing his tests, guaranteeing them that Midoriya was going to flunk this semester completely, Midoriya turned to alcohol. He spent his time excessively drinking and partying at the Viran Pub, much worse than Kacchan did when they were fighting.

It was worse to the point that he hasn't returned home for a whole week, skipping classes altogether and abandoning all forms of socializing from outside the pub.

Bakugo had enough.

"Deku, don't be such a child." Katsuki reprimanded him as he swiped the nth bottle that Deku drank that night. He came to pick Deku up as if he was a pre-schooler or something.

"Mind your own fucking business, Kacchan." He snarled, struggling to get the bottle off of Kacchan's hands.

"This isn't you."

"Didn't you notice that utterly I stopped being who I was?"

Kacchan frowned. He knew what he meant. Deku has been considering himself a failure for not being able to do what he formerly did best.

"Deku," Kacchan grabbed his wrist in a tight hold. "let's go home."

"I told you, I don't want to!"

"Deku—"

Kacchan suddenly felt a strong impact on his face. He fell a few steps backward, before toppling on the table behind him. Everyone stopped partying, yet the music continued playing.

All eyes were on Deku, the innocent lovely Deku, who just punched Kacchan's face.

"Bakugo!" Kirishima ran towards him, helping him sit up. "What the fuck, Midoriya?!"

"He's just drunk," Kacchan reasoned out, spitting out blood.

"That's not—"

"Back off, Kirishima." He shouted. "It's between me and him."

"But..." Kirishima trailed off as he watched Bakugo drag a surprisingly compliant Midoriya out of the pub.

***

It was cold outside, their breath was surprisingly condensing even though it was already springtime. Surrounding them were blooming sakura that seemed so beautiful under the pale moonlight.

"Kacchan," Deku trailed after Kacchan, his hands still tightly wrapped around his wrist.

The wind was blowing harshly around them and the sakura petals were scattered all around.

"Yeah?"

"I'm sorry,"

"I know,"

"I didn't mean to do it,"

"I know,"

"That will be the last and only time I'll do something so horrible to you,"

"I know,"

Clearly, this wasn't the first time they fought physically since often fought when they were just kids. But unlike what Deku promised, this wasn't the last time. In fact, it became a recurring event and Bakugo couldn't do anything about it and just accept each hit every time Deku gets drunk.

After all, it was his fault that Deku became like this.

***

"Deku, please stop!" Bakugo cried. "You've changed too much to the point I can even recognize you!"

But Deku could only stare at him with dead eyes, "This is the me you created."

Kacchan woke up with a gasp. He abruptly sat up. He heard a soft snore and he turned to his left only to see a sleeping Deku, nakedly snuggled upon his chest. He gave out a deep sigh, lying back on his bed.

Kacchan admired the beautiful being beside him, he couldn't help but cup his cheeks which were now devoid of baby fats ever since he's gotten thinner. He looked so peaceful, different from what he had become lately.

This was one of the days when Deku seemed like his former self: gentle and loving.

***

He was also soft and loving the first time he did Kacchan.

Maybe it's his experience as a bottom, Kacchan wasn't really sure. All he knew is that he made Kacchan good in ways he couldn't possibly imagine.

However, those days would completely vanish. The gentleness soon decapitated and was replaced with roughness.

"Deku," He moaned, struggling to get out of the ropes that bound him to the bedpost. "Please make me cum."

Deku only smirked, pushing himself inside of him with one quick thrust.

"Yes!" Kacchan sighed deeply. "Yes, Deku, please!"

"Am I making you feel good?" He whispered against his ear, roughly thrusting in and out of him.

The room was filled with the sound of slapping flesh and the scent of sex.

"Yes, Deku... You feel so fucking good inside of me...!"

"Don't think of anyone else, okay?" Deku said eerily. "Don't you ever think of Kirishima, that bastard."

"What—ngh!" Deku wrapped his large hands around Kacchan's neck, effectively pressing his carotid artery.

"Did you think that I didn't notice that every time we fought, you'd come crying to him?"

"I-it isn't l-l-like tha—" Kacchan felt the hands tighten around his neck.

"Don't fuck with me, Kacchan," Deku warned, pounding him even harder. "You don't know what I can do."

Kacchan struggled, feeling the life drain out of him. Just as he was about to fall unconscious, Deku lets him go and he felt the most incredible high he has ever felt. He came, jizz splattering all over his stomach.

"I didn't tell you to come, did I?"

"No, please!" Kacchan begged. "Please forgive me, Deku—"

"I love you, Kacchan. That's why I need to punish you for cheating on me."

It wasn't making love anymore, they were fucking like animals. It felt good but it wasn't at the same time.

He didn't know why but he wants his old Deku back.

But who was he to complain, it was his fault that Deku became like this.

***

Deku has been avoiding him lately. Whenever their eyes meet, they always had this look of guilt. He couldn't really place his finger on why he would act like this because they were doing alright.

His body was filled with bruises and scars from when Deku would throw bottles of liquor at him.

But they were doing alright.

He completely stopped talking to other people for fear of getting hurt by Deku, including his close friends such as Kirishima (especially Kirishima) and Ashido.

But they were doing alright.

He hasn't been going to class lately because all he did was take care of Deku who demanded all of his time.

But they were doing alright.

Deku was always punishing him during sex by tying him up, refusing to make him cum, choking him, shoving sex toys inside his ass while making him wear a cock ring, and a lot more.

But they were doing alright.

One day, Kacchan returned to their dorm, only to see the room half-empty. All of Deku's things were gone. What was left of his was his Captain America blanket.

Kacchan fell to his knees, tears streaming down his face as he wailed.

That's when he realized, they weren't doing alright.

But who was he to complain? After all, it was his fault that everything became like this.
