There's such great chemistry between all three of the main leads. The kid in this one is one of the best written kids I've seen in manhwa he is cute but not a saint beacause he is energetic and needy and hasn't been weened off yet. The female lead is practically this child's mother and dotes on him so much. The male lead is cold as he thinks the FL is scamming him but just wants his nephew back because he loved his brother. The best way I can describe the chemistry and dynamic between these two lovebirds is maid-sama(usui that mf I hated him) but better because the guy isn't a smug asshole he actually engages in his arguments with the FL and they're warming up to each other in such a warm way that it makes them all look like a family.
Its real slow paced and his reason for loving her is shallow also the kid starts getting real bland and annoying
