Due to a quirk somehow affecting the entire population of UA High School, brightly colored streaks would appear on people’s hair, coming in different colors and patterns too. People were shocked, of course, but then grew curious about how and why they randomly appeared.

After a week, they didn’t disappear. Several rumors spread around about what it meant. One rumor that popped up and sounded the most plausible was about it connecting soulmates.

“All this soulmate bullshit is fake.” Katsuki scoffs while twirling a strand of a neon rainbow streak on his hair which makes him pop out more. Little did he know, you had the same exact rainbow streak.

Once you with the bright hair passed by, he immediately realized what it meant, but tried to conceal his feelings of confusion and being flustered with his regular annoyed façade.
