sdfghjkl;' ok yes. Yes yes~ I need to talk about this kindergarten thing more with you your reply was lovely. Ok so little baby Yoosung is SUCH a crybaby. Bawls for anything. The others see him get comforted and Zen instantly bursts into fake tears to try to get attention While Luciel makes funny faces at Yoo to try and cheer him up to get praise from mc too. Baby Jumin still tells Yoosung 'daddy says when you're sad you should just wipe away your tears with money.' 
Jaehee thinks they’re all dumb and may brag about never crying. Additionally, Jumin is always begging his father to buy him things he thinks woman like (usually stuff he sees his dad give his girlfriends) such as rings, necklaces, ect. because he wants to give them to mc. Yoosung just lets her hold his teddy because his teddy is really important to him and that is The Ultimate™ for him. 
V is the father of these adopted children, except for Jumin who he’s only neighbors with. He doesn’t know how you can handle them all with the grace that you do, but he’s very thankful to have someone who can since the woman he adopted them with passed.
