The Wuthering Heights star will play Karen, the love interest of teacher Holly (Billie Piper) in the semi-improvised BBC serial.
"[Each episode is] half an hour long, for five nights on the BBC," the actress told Digital Spy. "It's [about] different situations of love [and] that's why I wanted to do it."
She continued: "It's very hard to get two female actors, put them together in a... relationship and not make it about sex.
Scodelario also admitted that she had been a fan of Billie Piper's music as a child.
"The first album that I ever bought was hers," she revealed. "But I didn't tell her that, because I thought it might put her off a little bit!"
Love Life - which also stars David Tennant, Jane Horrocks, Ashley Walters, David Morrissey, Vicky McClure and Lacey Turner - explores five overlapping love stories set in the same town.
