There is one step mom to the ML and his sister
We saw ML and his sister biological mother (she has light brown hair) she died. She gone.
We also saw the same stepmother in the chapter of bio mom funeral, while bio mom has face showed we *DON’T see stepmom face* only her blonde hair and the fact that she had an affair with ML dad. Who also died later on.
So we don’t know how stepmom looks like because we didn’t see her face in the one chapter she appeared in.
So I think she highly suspicious character in general, we don’t know how she looks like, but characters mention her a lot…
