Coronavirus isolation is creating new couples. This BBC report tells the love stories of 5 couples around the world whose relationships have been rushed by the coronavirus lockdown. The article contains some very interesting colloquial language, like "to juggle" (to deal with and balance two important things), "to have a blast" (a great time), "to cuddle" (to hug, to embrace), "to wrap up" (to conclude), "to grab" (to take), "to hang out with" (to go out with), "to shack up with somebody" (to cohabit), "a craving" (a strong desire), "to latch on to" (to get hold on to) etc. C1 students should be able to read the article without too much trouble.
And, in addition, here you can find a link to the BBC Reel video "How I Became Obsessed With a Stranger", where a Spanish young woman tells a compelling story of love, grief and Instagram obsession. The video has subtitles and half of it is in Spanish with English subtitles, so it can be accessible to B1 students.
