Rainy day
Katsuki hates rain, it's not a secret to anyone. He hates being wet and his quirk doesn't work like it should be.
But since they were children, Katsuki had noticed Izuku's behaviour toward him during this weather. And from many years he hated it, how the nerd was caring and trying to make Katsuki's life better.
Now, he can't help and fell in love each time.
"Kacchan!" Izuku says with a soft smile as he opens the umbrella. "Do you want to have dinner? I know a good place!"
Katsuki shrugged but takes notes that Deku's left shoulder is wet because that dumbass was giving the whole umbrella above Katsuki to protect him.
"Today, Daichi made an uncredible move with his quirk! I'm glad you're accepting to play the villain from time to time."
"You're too soft with them!" Katsuki growled gently. "Aizawa's sensei is right, you should be harsher toward them."
"Why should I when you alone traumatise them for an entire week?"
"If they can't handle me as a villain then they can't handle a real villain."
Katsuki sees the nerd rolling his eyes but says nothing. Then he notices the gently push from the nerd to go to the train station.
To avoid the rain.
They keep going like this until they reach the restaurant. And Katsuki's heart flusters when Izuku, who first sits in front of him, exchanges his seat with the one beside Katsuki so the blonde hero wouldn't see the rain draopping at the nearest window on their left. All that during his rant about their students, trying hard to not making it obvious of his moves.
But Katsuki sees them all. How Izuku is so devoted to him that it became a second nature for the nerd. He keeps talking, as if nothing was happening. All natural.
"I love you!" Katsuki says softly, almost on his own breathe.
"Did you says something?" Izuku asks, confused.
"Nothing. What do you want to eat? It's on me."
"Kacchan! I'm the one inviting you to dinner, I'm paying!"
"No argue, Izuku. Take all the things you want."
Izuku looks at him, trying to analyse his behaviour and that makes Katsuki chuckle and he ruffles the green hair.
"Stop being paranoid! I'm treating my friend, I can't do that?"
Izuku giggles and that's music to Katsuki's ears.
"Okay Kacchan, next time it's my turn!"
"Whatever nerd!"
Next time, it will be the right moment to propose.
On a starry night.
