If you come here hoping for cute story related childcare, just avoid and ignore it. It will waste your time.
But if you want typical shoujo romance, maybe this is for you.
The story are great and funny, especially the mystery related to the demon lord.
But it became garbage after the hero appears. His appearance just to annoy you. Yes, he annoy you not only with his cringe act, also author tryhard to make him into someone or something that just there to slow the progress of the FMC to demon lord.
Honestly, author literally just can focus the story related to the FMC to raised her children (because literally they will have 10, so every children will have different problems and arcs of course) and the progress to the demon lord. But he choose to make this character (Hero), and destroy the premised of the story. We literally can get the story between FMC and her children, but he give us with FMC daughter fangirling over the hero. Cringe as fuck..
