Why unlikely? Because, despite all the romance, its plot is fully based on a sexual transmitted infection. Hopelessly romantic twenty-something Dylan (Johnny Flynn) suddenly discovers he has chlamydia and is advised to contact all his (read: many) sexual encounters. Pair this plot summary with the fact that the show was originally called “Scrotal Recall” when it aired on British TV and you can be forgiven for looking the other way.

Underneath its awkward previous moniker, Lovesick is actually very funny, charming, and heavily romantic. Dylan is chaperoned by Luke (Daniel Ings, who you may know from Sex Education and The Crown), a seemingly confident but insecure business-school type, and Evie, Dylan's smart and cynical best friend, played by Antonia Thomas from Misfits. It soon becomes apparent that Evie and Dylan could be much more than just friends if only their timelines were to align.

Lovesick is a charming little series that homes in on the heart-breaking romance of failed relationships. Something you can easily find yourself watching many episodes in one take.
