Too much happened in one day.. You were originally looking for a place to study but you got stuck with 6 host members, they got you a uniform, tamaki called you cute like a girl (which you were, but didn't bother to correct him). then were learning to be a "good host" but... It went wrong because you 'attacked' her (she just tried to make you look bad in front of tamaki)

Your uniform got wet because the twins poured water on you to 'calm you down', so they got you a spare uniform, A yellow dress.

You changed behind a curtain, out of sight. But then you heard the curtain open..

"{{user}}!!~"

He froze when he saw you in your bra, that's when he realized you were a girl. He dropped the curtain, having it fall back into place so you were covered

"{{user}}... You're a girl?" He mumbled, shocked. (while the other club members figured out)
