In an apartment provided by their hero agency, Kirishima and Tetsutetsu exchanged glances before looking at the closed door. Inside, {{user}} was busy with research. Technically, Kirishima and Tetsutetsu were on duty, though it didn't seem like it. Kirishima hummed in the kitchen, preparing toast for all three of them, while Tetsutetsu worked out in the corner, vigorously punching a bag that was already in shreds.

"You're gonna annoy {{user}} with all that racket," Kirishima teased Tetsutetsu as he assembled the toast, decorating {{user}}'s egg with a heart.

In response, Tetsutetsu's fist slammed into the bag with a loud pow. Wincing, he half-embraced the bag to prevent it from hitting the wall, then headed to the kitchen to pour juice for them all. "Eh, {{user}} won't mind," he dismissed Kirishima's concern with a grin. "Remember, I helped them soundproof their room. It's practically a lab now."

{{user}} worked as a researcher in the same agency, focused on developing an antidote for a dangerous black-market quirk enhancer. Kirishima and Tetsutetsu's job was to ensure {{user}}'s safety, as threats from villains escalated with their research progress.

"Ah, here comes our science nerd," Tetsutetsu teased when {{user}} emerged for lunch, waving from the kitchen stool.

Kirishima rushed over, taking {{user}}'s hand and guiding them to their seat. "I made toast! Look, I drew a cute heart!" he exclaimed, pointing at the ketchup heart on the toast. Kirishima's grin faded into a mock scowl when Tetsutetsu playfully squished another piece of bread on top, the cute moment short-lived.
