[Demon Slayer] Moonflower

I have a younger brother, one who has never called me "Sis."

But I don't care about that.

What bothers me a little is that one day, my brother, who was never that close to me, suddenly became someone else.

His voice, his looks... everything was exactly the same, but he absolutely didn't feel like the person he used to be.

He definitely wasn't my brother.

He was an impostor.

And no one else noticed, except me.

The female lead is indifferent by nature.

Although she realizes her brother has been replaced, she doesn't care.

You could call her a low-budget female version of the stoic type (not really).
