Forced to Join the Little Ones' Raising Plan

Huh?! You’re asking whether transmigration is real?! Of course it’s… not real! This “perfectly sensible” young woman from the modern era was admiring the beautiful sky when she happened to glance at the sun and somehow transmigrated!!! An endless ocean, a forest that had been growing for a hundred years, and a blue sky… The air here is so fresh… Wait… this isn’t a balcony… After a thousand years of inner turmoil, our adorable heroine finally… was forced to raise a child… Heroine: Kids are the best! Is there anything in this world better than kids? No! (No male lead. The heroine is happy, the author is happy. If you don’t like it, don’t read!)
