I'm Here || BakuDeku/KatsuDeku

Chapter 15

Midoriya waved goodbye to Bakugou at the end of the day, smiling at the scowling boy who sheepishly returned the wave before going into his house. The messy-haired boy giggled, then started jogging towards the beach. That was where All Might had told him to meet when they'd made the deal after the sludge attack. Finally, Midoriya would be able to show how he truly was. He'd be a hero! He sped up his light jogging to a run, giddy with excitement and 'whooping' loudly in anticipation.
Once he skidded to a halt at the beach, his expression fell at the mountains of rubbish. All Might stood in a clearing-like area within the mountains of waste.
"It's a shame this beach is so jam-packed with rubbish." The trainer spoke, looking over his shoulder with a grin plastered on his face. "But not a shame that you'll be here to fix it!"
And with those words, Midoriya's training began.

~ TIME SKIP TO A FEW WEEKS LATER ~

Bakugou had been noticing little changes in Midoriya. How he'd keep on falling asleep in class, how he'd always look tired and how he'd become noticeably less weak. In his T-shirt the muscles in his arms had grown and Bakugou couldn't help but stare sometimes. He had no idea what was really happening, but he intended to find out. After class that afternoon, Bakugou walked back home with Midoriya. Once inside, he watched the green-haired boy through his window, waiting there until Midoriya left. He'd seen the other leaving his house at that time after school everyday for a few good weeks now, so his curiosity just grew.
The taller followed Midoriya secretly, all the way to the beach where he sat on a bench to overlook it. He watched as Midoriya ran towards a pile of old scarp metal, raising his eyebrow as he watched the figure try to push it along. "Is this what he's been doing? Clearing the beach?" He murmured to himself, jumping as he heard a voice behind him.
"Yes. Young Midoriya is doing an excellent job at it too."
Bakugou turned around and stood up, his usual scowl back in place as he took in the figure before him. They were about the same height, he noticed. While he was rather compact and well-built at the age he was, the other was skinny with an oversized top hanging over his crotch. It was All Might, but Bakugou didn't know this.
"Who are you? How do you know Deku?" Bakugou growled defensively, embarrassed he'd been caught talking to himself.
"My name does not matter. I am Midoriya's trainer. Who are you?"
"Katsuki. His friend." Was that what they were? Friends? "More or less." He added, glaring at the other.
The unnamed figure walked past Bakugou and down to the beach where Midoriya was resting against the large object he'd managed to move. The two talked and the man pointed to another object to be moved. Bakugou didn't think he'd do it, but Midoriya nodded to the man determinedly and ran over, pushing his weight against the trash and starting to push it across the beach.
It took some time, but Bakugou stayed for the entirety of it from the bench he sat on, watching in awe as the once-weak Midoriya picked up heavy objects on his back with seemingly no effort. At one point the temperature rose too much and Midoriya probably got too sweaty, so the figure on the beach pulled off his shirt and carried on with his work. Even from way up where he was Bakugou could see how much more his muscles had grown. He blushed softly and looked away, biting the inside of his cheek.

By sundown, Midoriya had cleared out a section and had waved goodbye to his trainer, starting to head back home tiredly. He hadn't expected to see Bakugou at the top and jumped as he spoke.
"Sup loser."
"Kacchan! W-What are you doing here?" Midoriya asked nervously, fidgeting with his hands.
"I've come to help you. You look tired as shit and probably won't be able to walk the rest of the way to your house."
Midoriya looked down in defeat and the next thing he knew he was sitting on Bakugou's back being carried to his home in a piggyback. He smiled, resting his head against Bakugou's soft hair and inwardly squeaking from happiness as the other didn't pull away.
