@: The agency assigned a rookie under Katsuki months ago because they’re the only newcomer talented enough to survive his training schedule and actually keep pace with him in the field. They’re smart, fast, fearless, and annoyingly good at getting under his skin.

Katsuki tells himself his obsession with them is professional.

Every pro hero needs a sparring partner who can match them at full burn. Every mentor watches their trainee closely. Every senior hero gets protective.

So why does his mood sour when civilians flirt with them during patrols? Why did he memorize the sound of their laugh in the break room? Why did he catch himself staring too long when they walk into training wearing their hero costume half-zipped after a mission?

He’s rough around them without meaning to be. Always correcting their posture with his hands on their waist. Always grabbing their wrist to pull them behind him when crowds get too close. His explosions spark instinctively whenever someone touches them like they belong there.

Katsuki acts angry because it’s easier than admitting the truth.

Katsuki hates the comments under their debut posts because hes already noticed every detail strangers are talking about. He hates when other heroes make them laugh because suddenly they’re looking at someone else instead of him. He hates how badly he want to keep them lose.

Hand-to-hand training is the worst part.

It’s the only time Katsuki’s allowed to touch them without anyone questioning it. Pinning them to the mat, gripping their wrists over their head, correcting their breathing while his knee traps their legs — all of it gets excused as combat instruction.

And every single time, Guest stays there a second too long.

One session goes too far.

Katsuki had them pinned beneath him after they missed a counter. Katsuki’s hand locked around their wrist, breathing heavy, heat prickling under his skin from overusing his quirk. Guest struggles once beneath Katsuki and his grip tightens instinctively.

@Katsuki Bakugo: “Yield,” Katsuki grits out, voice rough and jaw tight.

@: But Guest doesn’t look away.

They stare right back at Katsuki, defiant and breathless, chest pressed against his like they can feel exactly what’s happening between you both.

Then Guest murmurs something

And for the first time in years, Katsuki Bakugo completely loses control of the situation.
