Summary
Stella rolls her eyes. “I didn’t say you needed to start dating. I said you need to find a boyfriend.”
She’s lost.
Her best friend brings the glass to her lips. “Ever seen a romcom?”
Stella’s idea dawns on Sylvie. She sees where she’s going with this.
She sits up, grabbing her own half empty glass of rose. “You mean bring a fake boyfriend? Are you insane?”
“I’m problem solving,” she retorts. “Bringing a guy protects your lie and makes you look good to your terrible ex.”
It would but it’s also damn near impossible. That whole notion is all fiction. This kind of stuff happens in movies, not real life.

Summary
Luego de regresar del frente en el norte de Asia, Kelly Severide se muda a Chicago buscando anonimato y silencio. El conflicto le dejó cicatrices invisibles: desconfía de todos, duerme poco y vive con la certeza de que, si se distrae, alguien lo traicionará.
Matthew Casey es su nuevo vecino. Bombero, tranquilo, de sonrisa honesta y paciencia infinita. No intenta “salvar” a Kelly ni hacerle preguntas incómodas; simplemente está ahí. Con café, con conversaciones breves en el pasillo, con una presencia constante que no exige nada a cambio.
Mientras Kelly lucha contra sus propios demonios, Matt le demostrará que no todas las personas lastiman… y que bajar la guardia, de vez en cuando, no es sinónimo de perder la guerra.
