Everyone's so cute but why make the children be so mature? Mature in the sense that even their good and bad sides are not what adults act like. Or am I just a bit prejudiced and think that kids don't act like that? Stll though if they were 14+ it's still reasonable. But they seem ti be around 5-7 years old right. I understand the MC being more mature because of her circumstances. It feels a bit like let's make a story identical to other manhwas but make them children because it's cute, that will make it unique. Ngl I do like it though because it's cute. Basically I'm contradicting myself hahaha
