One day, Leah informs Simon about an online confession of a closeted gay student at their high school, known only by the pseudonym “Blue”. Simon begins communicating with Blue via email using the pseudonym “Jacques”. The two confide personal details and form a connection. However, their emails are accidentally discovered by another student, Martin, who is infatuated with Abby. After learning his secret, Martin blackmails Simon by threatening to make his emails public unless he agrees to help Martin win over Abby. Simon begins to look to his classmates for “Blue”.
At a Halloween party, Simon attempts to connect with Bram, but later walks in on him making out with a female student. During the party, Nick confides in Simon of his feelings for Abby. Simon lies to Nick, telling him that Abby has a boyfriend in college. Leah walks an inebriated Simon home, where she speaks vaguely about how she feels that she is fated to love one person very intensely; Simon believes she is referring to Nick.
Simon meets up with Abby and Martin at a local diner after he convinces them to practice lines together for an upcoming school musical. Simon bonds with their server, a classmate named Lyle, and believes that Lyle may be Blue. That night, Simon comes out to Abby and is relieved when she reacts positively.
At a school football game, Simon crosses paths with Lyle; before he can summon the courage to ask if Lyle is Blue, he finds out Lyle is actually interested in Abby. An upset Simon tells a pestering Martin to either “go big or go home” when courting Abby. Martin interrupts the national anthem and publicly declares his feelings for Abby. When Abby admits she does not share those feelings, Martin is humiliated and becomes the subject of intense ridicule.
