My Archrival Turned into My Little Sister. What Do I Do? She’s Too Adorable!

The writing is good, and the premise is alright, right? From the earlier descriptions, it seems the female lead has completely lost power. I can understand the part about her turning from an adult into a child and reconciling with her mortal enemy, but the amnesia is hard to accept. Seriously, if this is a story about a real child, why set it up as an adult turning into a child? In a story about a fake child, the purpose of amnesia is...

It's so incredibly good, it's hilarious and touching at the same time. Twilight's childhood was truly devoid of joy. Although she grew up remarkably well and raised herself exceptionally well, having her brother raise her again from childhood after shrinking is a kind of healing experience. These memories will gradually cover up the loneliness of the past. I hope Twilight is always happy.

Mumu is so cute! She's a purebred baby, one year and three months old. She loves rabbits, fish, and cats. She's lively, sociable, and a little mischievous, but overall very well-behaved. Watching her makes my maternal instincts kick in. The male lead and everyone else are completely captivated by our baby.

The female lead is so cute and adorable, it'll make you want to have a baby! 😳 The author really understands children and must have read many pure and beautiful picture books. The family storyline is already very engaging. I'm also really looking forward to seeing how the author handles the romantic relationships after the female lead regains her memories and her adult body.

I was absolutely heartbroken reading this! Oh, how can there be such a cute, well-behaved, and adorable baby? Of course, the older brother is cute too. I think the baby is very much like his brother, haha, they're both the narcissistic type, hahaha. I think if it continues like this, the sibling relationship will be very touching.

Actually, if you just read this novel as a story about cute kids, you'll find the interactions between the male and female leads are incredibly, incredibly, incredibly good!!! The children are portrayed so adorably!!! This is the first time I've seen a story that portrays children in a way that's both cute and not awkward!!!

It's good, but I want to ask when the female lead will regain her memories? Although the interactions between the female lead and the male lead when she was little were lovely, I always feel that it might be a little awkward for her to recall those moments after she regains her memories, because the female lead has a rather independent personality (this is just my personal feeling, please don't…

It's so beautiful! I don't have money to send you a gift, but I'll give you a five-star review instead!

It's alright. I think the premise is quite novel, but I'm curious about the female lead. When will she regain her memories? How long will the male lead have to support her?

The subject matter is good, and the description is heartwarming and lovely. Author, will Twilight be able to revert to an adult form later on?
