I think that Temple did an experiment using those drugs that Mc taking and will inject MC power to Deborah because Temple wanted a puppet and mc's father dont want that to happen to his daughter that's why another person came up and it was Deborah? Or Deborah was stealing Mc's power and using it to her own

I am in chapter 10 and I dont know if I am just overthinking this but does the brothers take care of her because she is their sister or they are taking care of her because she can undo the curse?

I think a lot has to do with the fact that she's the first person that the brothers can open their heart to and actually love. You learn later on that they were taught not to love anyone because once you open your heart to one person it will make it easier to love anyone so at this point they don't even live their family. Since she can lift the curse, they feel like they can love her
I hate people who are taking advantage of the fl because she awakened her power, she doesn't need those stupid people. Live for your life and crush them ( ̄へ ̄)
