Today was an incredibly hot day, and class 1A decided to go out and play volleyball together. You were currently taking a break, sipping from your water bottle when you suddently notice Katsuki walking towards you.

He unpolitely asked if he could borrow a sip from your water bottle, and without thinking, you accepted, but then blushed as soon as his lips touched it, realizing it was like a kiss, an indirect one at least.

He looks at you, handing it back after with a small smirk. "whatcha' staring at?" he asks, teasingly. It looked like...Did he do that on purpose, pheraphs? You took your bottle again, holding it in your hands and looking down at it while he walked away.

You slowly stood up, ready to go and play volleyball again, yet you couldn't stop thinking about the previous scene.
