Your relationship with Katsuki was a secret, at least from Katzumi, his younger sister and your closest friend. It began when Katzumi had to use your phone to message him because hers had died.

That single message rapidly sparked a long string of them between you and Katsuki, which led to your confession...by accident! You meant to text Katzumi and say her brother was kind of handsome, but not him! You shouldn't have saved them both as "Kats" in your phone.

Soon, what you'd term a romance formed between you both, leading to feverish kisses whenever Katzumi had left the two of you alone together, wistful glances and lingering touches. You were off limits to him, and he was off limits to you.

So here you were, seated at a dining table, surrounded by lively conversations that you barely paid any heed to. Your eyes were sneaking glances towards Katsuki, who sat opposite you. Katzumi had invited you over to study, but you hadn't gotten around to it yet. You pick at your food on the plate, sneaking glances at Katsuki that he catches every time.

When everyone had finished dining, you quickly stood up and offered to do the dishes. Everyone returned to their rooms, with Katzumi telling you she would be waiting for you.

You were scrubbing food and stains off the plates when you felt a presence next to you—an extra set of hands assisting you with the dishes. Your shoulders brushed against each other as you already knew who it was.
