Description: Bakugou decides to make you dependent on him in a way you never saw coming

"...And I just really like you. You're not like all the other extras." Bakugou's heart pounded in his chest. This was the moment- what he'd been building up to for years.

Your face fell and so did Bakugou's heart.

"I'm sorry, but I don't feel the same way. I prefer someone who's soft and kind, someone like..." You let the words hang in the air and Bakugou clenched his fists in anger. He knew what you were alluding to.

Someone like Deku.

How could he be surprised? You spent all your free time with that little freak. There was little doubt in his mind that the feelings you had for Deku were mutual.

Anger bubbled up inside him and he began to yell, "Are you fucking stupid? How can you see any future with that runt? I'm a hundred- no- a thousand times better than him."

Tears flooded your eyes and a soft "I'm sorry" floated out of your mouth.

"You'll regret this," Bakugou seethed, "You'll change your mind."

But as he stormed away, he knew his words were empty. You would never change your mind- he had just proved he wasn't soft and kind and all the other things you saw in Deku but never him.

Bakugou didn't go back to the dorms that night. He spent the evening through early morning pacing the grounds, just thinking about what he could do to change your mind. Nothing could soothe the ache in his chest as your words repeated in his head.

Soft and kind was weak. You didn't know how much you needed him. What if you got robbed? You wouldn't want sweet Deku then. You would want big, strong Bakugou, who'd kick that robber's ass. When your bones were broken and you were bleeding, who would protect you? You thought you wanted soft hands and a sweet smile... You didn't know what you needed.

He came to a stop outside the science building and caught sight of the janitor going inside. A thought struck him like lightning. He normally pretended not to be paying attention to you, but he remembered you and Uraraka talking about her science project.

One drop would shrink a building, an object... a person.

A grin curled across Bakugou's face.

—-------------------------------------------------------------

The tables were full of students, but Bakugou managed to pick out a spot next to you. The food appeared magically on the table and he quickly seized the pitcher of orange juice and poured a generous amount into a cup.

"Here," he said gruffly to you, handing you the drink. You looked relieved, probably thinking he had gotten over your rejection.

How wrong you were.

"Thanks, Bakugou," you said softly. You brought the cup to your lips and took a few sips, unaware of how closely Bakugou was watching you.

Suddenly, the cafeteria shot upwards, ballooning around you. You thought, for a moment, that you were fainting, but the dizziness wore off and you realized that everything had gotten much bigger. Or, rather, you had shrunk.

A familiar face leered down at you, his red eyes wild with triumph. "Bakugou!" you cried out in terror, "Help me! I don't understand what-"

A giant hand shot out and grabbed you. You were essentially the size of his index finger, so all the kicking and punching you did didn't cause so much as a mark on Bakugou's hand.

"It's okay now," Bakugou cooed, "You're safe with me."

He cradled you to his chest while you began to sob, heart-broken by the betrayal. It didn't matter what you did, he wasn't listening to you anymore. He just grinned at the way you curled up in his hand like you belonged there.

Finally, he deposited you in his shirt pocket and stood up, causing you to fall down at the sudden movement. Bakugou walked out of the cafeteria and all the way to his dorm room. Once he arrived, he pulled out the shoebox he'd been working with early in the morning.

The shoebox contained a doll's bed and blanket with a cotton ball pillow. He gently picked you out of his shirt pocket and set you down on the little bed. You stared up at him in absolute horror, cheeks stained with tear tracks.

Bakugou smiled, feeling powerful and in control, "You're safe now. I'll take care of anything. But don't try to run away. I can't stop you from being crushed or lost if you do that."

"Please let me go!" you screamed up to him, "Please, I'm sorry I rejected you!"

Ignoring you completely, Bakugou said to himself, "And maybe one day, I can un-shrink you and we can get married."

Your eyes went wide and the tears began again, "No! I love Izuku!"

Instead of getting angry, Bakugou stroked a fingertip over your hair as gently as if you were a doll of china. "I know you think you love him," Bakugou said, "But he wouldn't do this for you. He wouldn't keep you safe like this."

You didn't respond, the whiplash from his delusions striking you made you feel lost and afraid. Bakugou's smile twitched at the corners, wavering between warmth and something darker. He rested his chin on the edge of the shoebox, red eyes focused on you.

"I'm doing this because I love you," he said softly, "You're too stubborn to see it right now, but you will one day."

And for now, Bakugou thought blissfully, You'll be completely dependent on me!
