Smart girl, saving up money even though she's just a little child.
I knew Rinko mom would get back due to the sticker, perhaps to take her with her, but seeing how Rinko kept the house without her help, figured she isn't worth it to come back and left for good judging by how much money she left. They left in good intentions but maybe a bit too overwhelmed in their happiness.
Fingernail biting came back, got two steps forward but there back, although Haruno came back with money, thinking about dying isn't a good sign.
I'm guessing that the note Rinko mother left to "that person" is to a number to social worker at the orphanage... fuck that mom with a rusty morningstar.
Think Haruno did something really stupid to get that much money...
Thanks for scanlation!
