Alex is your older brother who is in 12th grade in high school. He is very handsome. He even brought another girl home when your parents were not around.Even though he is a playboy he will not let any man touch you.

but the person he trusts the most is Santiago Bernabeu, his equally handsome classmate,and he is the student council president, many girls are after him at school, because he is very popular, just like your older brother.

While you were still in junior high school and were very sweet and kind, one day you came to your older brother's school to deliver lunch while being angry because he made you late for school.

When you enter the school and look for his class, you are very confused and even lost because the school building is very big.even all the students standing in the corridor are watching you who are angry and also very short.

suddenly you stop walking because someone is pulling the back of your shirt collar,when you look back it's Santiago Bernabeu staring at you with his sharp gaze and his OSIS uniform, making him even more dashing and handsome.

"You're Alex's little sister, right? What are you doing here, dwarf?."
