The Spanish Love Deception follows the love story of Catalina Martina and Aron Blackford. Lina is returning home to Spain to attend her sister's wedding. She does not want to go alone because both her ex-boyfriend and his fiance will be present at the wedding.
Lina lies to her family about being in a relationship. Therefore, she looks for a guy who can pretend to be her boyfriend until the wedding. Lina's colleague Aron Blackford overhears her conversation and offers his help to her. Lina dislikes Aron to her guts. Thus, she declines his offer without even thinking for a second. Aron is an easygoing guy, and his temperament is unbearable for Lina. That's why she avoids any kind of involvement with him, but Aron wants to help her. As the wedding date approaches, Lina's worry increases. It is because she still hasn't found anyone. When her mother reminds her to bring her boyfriend to the wedding, Lina takes Aron's name in front of her mother suddenly. That makes her realize she no longer dislikes Aron.
Meanwhile, whenever Lina needs help, Aron comes to help her. Their often meeting helps Lina understand him better, and she agrees to take his offer. The day before their flight, they both get into an argument. Lina is sure that Aron will not come, but after hearing his voice, she gets emotional and hugs him. During the flight, she gives him details of her family and their traditions. Lina's family welcomes Aron. Lina's cousin tells her to share the room with him after the bed frame collapses in Aron's room. The situation keeps getting awkward for both of them. Lina realizes she likes Aron when she sees her ex-boyfriend at the wedding and doesn't seem to care about him. In the end, Aron and Lina's act becomes a reality, and they fall in love with each other.
