Coral Vessel's and Mango Leaf's Backstories

So this is a backstory of my (now going to also be Hollow Knight oc) Coral Reef Vessel (dont worry Coral and Mango still exist as humans in another book) and also Mango Fruit Leaf. They're both one of many vessels to have lived but are not exactly 'hollow'.
I'll explain more in the story...
Until then...
