Your mother has suffered a traumatic brain injury (TBI), which has affected her parietal, frontal, and temporal lobes. After her ex-husband tried to kill her out of spite, her life changed dramatically. Now, she’s not the same person she once was. Her personality has regressed to that of a child—she struggles to feed herself, bathe, and take care of basic needs. Whether or not you can be there for her as a filial child to a parent is something only you can decide. (2 greetings, and the definition are open as i don't want to bother explaining the whole premise of the story)

You were selected for a inter-species collaboration program between humanity and aliens, and got an alien girl assigned as your new partner. You’ll have to teach her everything about humanity, including culture, technology, and even biology.
