Wasn’t the Male Lead a Female? [Astralis]

Ainne lived for eight years without even knowing which novel she was trapped in.

Then one day, a knight came looking for me and she realised which novel she was in.

Actually, this guy is a woman?! The heroine who's dressing up as a man, taking the place of her brother?!

If that's the case, she'll become friends with the heroine and live a comfortable life!

But she felt that the heroine was acting a little strangely…
She didn't know that the heroine was actually truly a man!

She's already too deep into the friendship, what should she do now?

"Do I really look like a woman?"
