Riley Harlow is the main character in The Sims: Life Stories. She came to the town of Four Corners and arranged to stay with her Aunt Sharon Foss after she had lost her job. After Aunt Sharon leaves suddenly on a business trip, Riley is welcomed by Mickey Smith, Fiona Fortuna, and Agora Tchotchke. The next day, she invites Mickey over, not knowing he will bring Agora with him.

Riley tries to flirt with Mickey, and Agora gets angry at her. She storms off in a huff, leaving Mickey at Riley's house. Mickey calls Riley the next day and asks her if she wants to go to the Starlight Cafe and Market, where they share their first kiss, and become boyfriend and girlfriend. Later, Fiona calls Riley saying that her ex-boyfriend from high school, Dylan Kincaid, moved into Four Corners a few weeks before she did. He calls Riley, and invites himself over to her house for dinner. They fall in love again, and Riley is conflicted about her feelings for Dylan and her relationship with Mickey. Riley invites Mickey to the gym, not knowing they will meet Dylan there. Mickey finds out Riley was dating Dylan, and dumps her on the spot.

Dylan later goes to Riley's house to comfort her. Feeling particularly down, Riley decides to go to the boutique. She invites Dylan, but he makes the excuse that he has to work. So she then goes alone, and sees Dylan there on a date with Ashley Sinclair. After attacking him, he dumps her, and Riley discovers Dylan dropped his wallet during the fight. She takes the money, and spends it on clothes, but goes home when she sees Mickey with Agora, since the two of them are engaged now. Riley then decides to make up with Mickey, but when they finally do, he has to go and marry Agora.

Riley is devastated, and things only get worse when Dylan shows up yelling at her for wrecking everything. Aunt Sharon shows up with the police, and Dylan is arrested for kidnapping Sharon and holding her hostage in his basement. Riley finds out Agora was involved too, and goes to Old Grove Gardens to stop the wedding between Mickey and Agora. When she gets there, she tells Mickey everything, and Mickey leaves Agora at the altar.

Agora is furious at Riley, and gets in a fight with her. Riley wins, and Agora is arrested. Mickey asks Riley to marry him on the spot, and they go on their honeymoon to the Simaican Isles, a play on the Jamaican Isles. When they get back, Sharon announces to them that she is giving them the house, and leaves on a date with a guy she met over the internet. Riley then becomes pregnant, and she and Mickey throw a house party to commemorate the occasion. Riley then has the baby during the party, and this is where the storyline ends.

But it's not over yet! Riley, Mickey, and their baby are now available in the neighborhood view as a playable family.
