Alina Pop is a telesales agent at Underworld, who initially came to the country as a victim of human trafficking.
Living in squalid conditions after having been transported to the UK from her home city of Brasov, Romania by a human trafficking ring, Alina began a friendship with handyman Seb Franklin in 2019. With the assistance of Seb, and undercover police informant Jan Lozinski, the trafficking was exposed and Alina was rehabilitated by the Salvation Army. The following year Alina returned to the street to find that Seb had moved on from their brewing relationship with Emma Brooker, and Alina was invited to move into the pair's flat after securing a job at Underworld.
Since then Alina's presence caused Seb and Emma to break up, although the trio remained friends. Alina was also persued by David Platt, who was suffering in the absence of his wife Shona, and Adam Barlow.
In 2019, Alina worked as a nail technician employed at Sparkle Lounge, which was being used for human trafficking. Alina met Seb, who later became aware of the situation and promised to help her get out of it. Seb called the police, who went into the nail bar and arrested the human traffickers.
Alina returned to Coronation Street in 2020, and got a job working at Underworld.
