Input: Question: How many students attend the school Celyn received an acceptance letter from before traveling alone to Manila? Passage:Celyn Buenaventura (Kim Chiu) was an ambitious and kind working-class girl living in Cebu with her widowed mother, Theresa Apolinario (Cherry Pie Picache). One day, she received an acceptance letter from the University of the Philippines Diliman, but Theresa was furious and refused to let her go. Celyn thus travelled alone to Manila, and upon arriving was employed by the owner of a carinderia, who allowed her to sleep in the eatery. On the first day of school, Celyn met Margaux Marasigan (Maja Salvador), the daughter of Julio (Ariel Rivera) and Beatrice Marasigan (Janice de Belen), owners of the famous Memorata shoe company. Margaux lived the luxurious life of an heiress, and Celyn looked up to her in admiration. Celyn also met her friends, Ethan Castillo (Enchong Dee) and Liam Lagdameo (Xian Lim); she and Liam were initially irritated with each other and she remembered Ethan from a childhood incident where he seemingly saved her life. Celyn and Margaux eventually became best friends. Celyn found out that Ethan and Margaux were lovers. Margaux may have led a life like a princess, but she was often concerned about her mother's strictness. Margaux follows everything Beatrice says, but she knows that her family is against Ethan. They kept their relationship a secret. Celyn found out that Liam has a lifelong crush with Margaux, who was his best friend. They promised not to tell anyone when Liam also found out Celyn likes Ethan. Beatrice showed great dislike to Celyn because she believes Celyn is changing Margaux, while Julio defended Celyn. Theresa decided to moved to Manila with her father, Zacharias (Ronaldo Valdez), and was found by Julio, who confronted her and asked where she took his real child. Theresa tried to hide Celyn from Julio, but they already met each other. Ethan's father ran away because Lucas thought that he is the one who took his money.
