Okay, so I realized that was cheesy and vague. Here's a better explanation.

Ever since Sabrina was a child, her brother has been saying that she's so ugly and stupid, that she would never get a boyfriend. Then it gets kinda similar to YanChan and Senpai. She drew a picture of a boy with purple long hair and red eyes. She thought that he would be her boyfriend one day. She imagined that he would be kind, smart, dramatic, and loyal to his friends. On her first day at Akademi High, her brother told her to follow him. They went to the rooftop, and Gema began to continuously hit and kick Sabrina. Midori, who walked onto the rooftop, saw what he was doing and went to tell a teacher. The teacher sent him to the guidance counselor. Midori tried to send her to the nurse's office, but on the way, Sabrina passed out. While Midori was trying to wake her up, Tsuruzo walked by, noticed Midori's problem, and helped wake Sabrina up. When Sabrina saw Tsuruzo, she noticed how he looked and acted like the boy from her childhood drawing. She was immediately infatuated with him.

Sorry that was so long. You asked why she fell in love with him, and I wrote a whole life story XD
