the hero is MC's husband who also reincarnated but don't have the memories from his previous life. In their previous lives, they had 2 kids: the daughter was summoned as a hero in the new world and the son was reincarnated as their future baby
Lmao she is amazing in her own way. A bit concerned about the part where she had a daughter and yet falls love with hero younger than her tho...
but with the spoilers leixia and arliadlaw gave, i guess that's understandable. Also explains why she thought he was her fated one since the first time they met
