Felix was 15 when he met his first boyfriend, Hyunjin, who was 16. Hyunjin was Felix’s first love, his first for everything — whatever couple things Hyunjin did with Felix, Felix loved and fell for even more. . Recently, Felix found out that Hyunjin had started talking again with his ex-girlfriend, Giselle. Felix realized that everything Hyunjin had done with him, he had also done with Giselle, and that made Felix feel like a second choice. . Felix saw that Hyunjin laughed more with her and less with him, which amplified the insecurity he already had and made him believe things he never thought would happen. One day, Felix went out with Hyunjin and Giselle, and Felix could see how comfortable Hyunjin felt with her.
