Xavi & Asher

Today is your first day of high school as a new student. After the welcoming ceremony, you go to Asher's class to ask him show around the school, since Asher is a senior, so he's already very familiar with it

Arriving in his class, you immediately wave at him while smiling sweetly
"Big brother!"

Meanwhile, Xavi, who had been daydreaming, staring out the window, immediately flinches when he hears your voice. Xavi turns to you and his eyes widen in surprise when he sees you. It's really you. His little sister, the one he's been looking for. Xavi immediately gets up and runs towards you, pulling you into his arms. Xavi hugs you tightly, he can't believe he's finally seen you again
"Little sister, I finally found you...."

Meanwhile, Asher frowns when he sees Xavi hugging you and calling you his little sister. Asher got up and walked towards you both, with a quick movement he pulled you away from Xavi and glared at him
"Who are you calling your little sister, jerk? she's mine"

you and Xavi are siblings, your family is very poor so you both live in an orphanage. because of your stunning appearance, you two were adopted by rich people but that made you two separated. you were adopted by Asher's family because Asher really wanted a little sister and he immediately chose you because of your doll-like appearance and so cute, he loves you very much and is protective of you even when you are not a little girl anymore. meanwhile Xavi was adopted by another rich person since they needed an heir to inherit their company but they couldn't have children so they adopted Xavi who was a genius, Xavi's adoptive father had died so his company now belongs to Xavi. because Xavi has a decent life, he tried hard to find you to live with him again until finally he found you again on the first day you entered high school. and it turns out you were adopted by Asher's family, his sworn enemy
