Growing Pains

Summary:

Everyone knows Bakugou can be spiteful when someone does him wrong. However, we all know how impulsive and arrogant he can also be. Unfortunately Kirishima gets the brunt of it.

Notes:

I need somewhere to write angsty shit about these two to keep my love for them under control.
I want to write more oneshots of these two so please send me prompts to keep me motivated; I want to be a part of the hype <3

Chapter Text

'How much of that did you hear?'

Bakugou cautiously observed Kirishima from under his lashes, head down in shame and guilt, bracing himself for the fallout. Kirishima's eyes stared back blankly, trying to figure out who the man was in front of him. 

'So it's true?'

Bakugou flinched under the accusation. Oh God, Kirishima had heard it all.

The redhead was looking at him in a way Bakugou had never seen before. There was currently no sparkle to his eyes, no admiration. Bakugou's stomach dropped under that look when he realised what it was. Confusion. Hurt.

'It isn't what it sounded like.' 

Kirishima furrowed his brow, the edges of his mouth downturning even further.

'Did you or did you not fuck-' Bakugou jolted at the harshness of the word as it came out of the other's mouth, '-somebody else whilst you were in a commited and, as far as I was aware, happy relationship with me?'

'Kiri...'

Bakugou reached out his hand to the other as he noticed the once bright eyes of the man he loved beginning to well up. His heart broke at the notion that he'd caused this. Kirishima slapped his hand away, blinking back the tears that were threatening to fall, anger now overtaking his features.

'Yes or no?'

The question came out quiet and pained, Kirishima's voice breaking slightly indicating that he was on the verge of breaking down.

Bakugou could feel his sinuses beginning to sting as he swallowed away the threat of bile rising in his throat. He needed to make Kirishima understand that it was a stupid mistake that was brought about through shitty communication and him jumping to conclusions.

'Eijirou, please, let me explain-'

'YES OR NO? It's a simple fucking question Katsuki and I swear to God-'

'Yes.'

Kirishima and Bakugou both froze. The word hung in the air like a gunshot as the sentence that Kirishima was in the middle of saying got caught in his throat instantly. As he looked into the guilt-ridden eyes of the one person who he trusted to never hurt him all his anger seemed to leave him as his entire posture slumped in defeat and incredulity with a sharp exhale. 

Bakugou could literally see the heart of the only person he'd ever loved tear to pieces in front of him, and the intense fear of losing the one thing that kept him grounded, the one thing that made his life with living, hit him like a truck.

'I love you, Kiri, and I'm so sorry. I love you so fucking much-'

'Stop.' Kirishima held up his hand, interrupting the other into silence. 'I can't do this right now. I need some space to think. We'll handle this later.'

Kirishima turned and started walking away leaving Bakugou rooted to the spot, trying to come to terms with the fact that he'd done this, and he deserved this. The seconds passed and Bakugou dropped to his knees, words failing him as the tears finally spilled over.

All he was able to do was watch as the love of his life walked away from him without looking back.
