So the 2nd volume wasn't adapted?
Shame, since it was about a heroine that got a harem getting her memories back and deciding to end her harem and give everything back to the women she stole the men from in 24 hours.
Same setting but obviously Alexandria and others are just mentioned, Alexandria also has a daughter...Lucia's daughter, in that Lucia gives birth, refuses the baby(i guess because it's proof that the Isekai Lucia and the prince had slept together) and Alexandria adopts her.
Lucia's daughter by all rights is genuinely nice and loves her adoptive mother, she is just there in the background though, i guess in the 2nd game, she wasn't the heroine or any of the love rivals, and neither are any of Alexandria's sons...probably because they didn't exist in the 2nd game, which is likely the only reason why she didn't do anything before the 2nd protagonist decided to change things, she wasn't messing with any of her kids, so she could do her own harem for all she cared.
