"You're young, handsome boys, you must have dated a little? Are either of you seeing a lucky lady? Bakugo-kun?"
When he didn't speak right away, Eun's heart fell into her writhing guts. There it was, what she knew would happen eventually. You'll be nothing but a stain on his career. Endeavor was many things, and correct about that was one, his hurtful words a last-ditch effort to separate her from Shouto when they dated months ago. She'd lived with that since, thinking about it every time she went out with someone despite the risk of being recognized or photographed, and now, it must have clicked for Katsuki too. She buried more of her face into her sweater, not wanting to watch the public rejection, to see his face when he relegated her to a secret. A fling.

Katsuki and Shouto do a televised interview and things go a little sideways.
