A Perpetual Response to Thee

Alessandro, a man who has a secret love for his friend who likes someone else, Catalina. Catalina frequently toil to get the attention of the guy she likes, Louis, but Louis doesn't treat her seriously. For Louis, love is just a mere game, and Catalina is just a tool of his amusement. But for Alessandro, Catalina is more precious than jewels. Catalina frequently write a message for Louis to notice her, but before she gives it to him, she often asks Alessandro first if the message is captivating. While Catalina constantly doing it, Alessandro genuinely wishes that he is the one being loved by Catalina, and that perpetually triggers him to write his response through his notes secretly to Catalina's written words. Will Alessandro keep his love for Catalina forever? Or Will he take the risks of confessing his love, thinking that their friendship might be eradicated if he does it?
