⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.
Summary
The chapter opens with Rosie Graham alone in her best friend Lina's apartment, having fled there after a section of her own apartment's ceiling collapsed hours earlier. The collapse exposed her upstairs neighbor Mr. Brown in a compromising state, adding to her already terrible day. Now, late at night, she hears someone rattling the locked front door and then banging a shoulder against it. Convinced it's a burglar, she freezes, then tries to assess her options: the apartment has no hiding spots, no weapons, and no fire escape.
Her phone pings with a notification from a motivational app, giving away her presence. She lunges for the phone, knocks over a stool, and the noise alerts the intruder. He calls out, asking if anyone is home. Rosie, panicking, threatens to call the police. She actually dials 911 and speaks to a dispatcher, while the man on the other side of the door insists he has a key and claims this is a prank. He mentions his “little cousin” and says she’s “very funny and highly creative.”
Rosie begins to suspect the intruder might be one of Lina's relatives. She ends the 911 call and asks who his cousin is. He says “Catalina” and provides specific details about her—her birthday, her appearance, her loud laugh, and a story about a snake prank that led to him being kicked. He also mentions that Catalina is on her honeymoon in Peru with Aaron, and that he missed the wedding.
Rosie realizes this is Lucas Martín, the cousin who missed the wedding—the one she had secretly hoped to meet. She had kept a screenshot of him on her phone and had imagined meeting him at the wedding. Overwhelmed with embarrassment and anticipation, she unlocks the door and throws it open. Lucas, who had been leaning against the door, falls backward onto the floor. Rosie blurts out that his hair is longer than in the photo she has, then blushes deeply. Lucas looks puzzled but then smiles warmly, introduces himself as Lucas Martín, Lina's cousin, and the chapter ends with Rosie knowing exactly who he is.

Character Development

Her internal monologue reveals her tendency to catastrophize and her self-deprecating humor.

Why This Chapter Matters
This opening chapter establishes the premise of the novel: Rosie, a romance writer (implied by her later profession, though not yet stated), is forced to share space with Lucas, the man she's been secretly admiring. The chapter introduces the central conflict of mistaken identity and the comedic tone that will likely carry through the story. It also plants the seeds for the “roommate experiment” hinted at in the title—though the experiment itself hasn't been named yet, the forced proximity and the chemistry between Rosie and Lucas are set up here. The chapter's humor and Rosie's relatable voice draw readers in, while the cliffhanger of Lucas's introduction leaves them eager to see what happens next.
Study Questions and Answers
- Why does Rosie initially believe the intruder is a burglar, and what clues make her reconsider?
- Rosie assumes it's a burglar because someone is rattling the door and banging against it without knocking. She also recalls her past experiences in questionable neighborhoods. She reconsiders when the intruder mentions his “little cousin” and provides specific details about Catalina, including her birthday and a personal story about a snake prank. These details convince Rosie that he is a relative, not a random criminal.
- How does the chapter use the motivational app quote “If opportunity doesn't knock, build a door” to reflect Rosie's situation?
- The quote appears on Rosie's phone at a moment when she's trapped and panicking. It's ironic because she's literally behind a door, and the “opportunity” (Lucas) is knocking—but she's trying to keep him out. The quote also foreshadows that Rosie will need to take action to create opportunities in her life, which she does by opening the door, albeit clumsily.
- What does Rosie's reaction to Lucas's appearance reveal about her feelings for him?
- When Rosie opens the door and sees Lucas, she immediately notices his longer hair and blurts out that it's different from the photo she has. This reveals that she has been closely studying his image, confirming her secret crush. Her intense blush and her inability to form coherent sentences further show her nervousness and attraction.
