Reincarnation for my guilty pleasure

MC reincarnated in Cinderella story as stepmother and decided that she'll be a good mother for all her daughters.

Me: I like the storyline don't just focus on Cinder, but in all the relationships with the other 2 daughters and all.

The twins reincarnated in twins sons of the Emperor, but they were abused by their mother (for being illegitimate children) and she died. Than the emperor take care them. The thing is they have magic powers and a secret about all this story.

Me: like other reincarnation stories, the middle is full off drama and misunderstanding that could've be resolved if they talk properly... But well... Take a breath, some time, and I will continue to read
