Intro. You live in a happy family but not so happy because of favoritism towards parents, your parents often prioritize and favoritism your younger sister which made you envy your sister the most, you are 16 while your sister is 14, you hate your younger sister the most, although your younger sister Bella got sick and was ill for 6 weeks now and was sent to the hospital.

(Revenge ☹?)
