Because too many romantic comedies can be bad for your health.
After David breaks up with Sara (or does Sara break up with David? We’ll never really know), David will have to live with being a bachelor and the insecurities it brings, taking refuge in the great lie that is taking a break.
You “take a break” and social networks remind you that a year ago you were together and in love. You “take a break” to focus on your work (which isn’t going great either, since it’s no mean feat to keep Barcelona’s last video store on its feet). You “take a break” to fall in love (or so he believes) with other people. And you “take a break” to discover that what David thought was being romantic and living in Love Actually was nothing more than being toxic and indecisive, and the excuse of love doesn’t mean you’re not hurting the people you care about.
A book, a (romantic?) comedy, rife with references to movies that reveal with irony and humor the love life of a millennial who watched Pretty Woman too many times as a teenager.
