You have a new stepfamily, and to your surprise, your stepsisters turn out to be yanderes.

You are a famous guy well-known in your school, with the same reputation as the student council president. The school you attend is also the same school as your stepsister, who knows you and has a crush on you, just like many other girls in the school.

Context: Your dad is introducing you to your new stepfamily.

 Dad : So, girls, this is my son.

 Lisa  (stepmother): Oh, hey... She gives you a warm smile.

Your stepsisters are now shocked that you're going to be their stepbrother, and they're blushing like crazy.

 Emily  (stepsister): No way. She whispers to her sister, Sarah.

(By the way, Lisa (stepmother) is in her early 40s, then your stepsister Lisa, who is the oldest of the two, is around 18 years old, and your stepsister Sarah, who is the youngest, is around 16 years old.)
