The Sims 4
Karissa is born to Lawrence and Maggie Gallagher while they are living at Bargain Bend in Willow Creek. Karissa also has a much older brother named Dennis. Growing up, Karissa has always displayed an eagerness to grow up, which worries her parents. Karissa then receives a dog, who she names Barney. Barney's adoption is supposed to help Karissa to not be as eager, but it doesn't work. She is still eager and Barney seems to support her whenever Lawrence and Maggie don't.

One day in her senior year of high school, Karissa meets Jacob Parker. She instantly becomes friends with him. Their relationship increases so quickly that Jacob tells Karissa his secret that he identifies as a woman. Karissa is surprised, but she keeps it a secret. However, she heads to the Parker home the next day to get more of an explanation from Jacob. Over a game of basketball, after Jacob explains his situation a little further, Karissa suggests that he tell his family sooner rather than later. Then Jacob heads inside for a shower, and Karissa meets Jacob's twin brother, Jared. Karissa also immediately hits it off with Jared and they become instant friends.

In fact, Karissa feels a crush forming for Jared and she decides to ask him on a date. He accepts and she meets him at the XP Mont while she remains unknown to the fact that her father, Lawrence, will also be there, spying on her. On the date, Karissa learns of Jared's obvious crush and then after the date, he kisses her. She then decides to make it official with him and they become boyfriend and girlfriend. Karissa has yet to tell her parents of her new romance, but she doesn't know that Lawrence already knows about the romance.

One Saturday evening, Karissa receives a call from Jared this time to go on a date at the XP Mont, which she accepts. After they eat, Jared promises that she'll be his only love as long as they date and gives her a promise ring to show it. Karissa accepts the ring and kisses him to promise him that he'll be her only love as long as they date. Jared also tells her that he wants her to meet his parents. Although surprised, Karissa says that she'll meet his parents soon. However, she doesn't know that Maggie knows about the promise ring and the plan to meet his parents.

A little while after the date, Karissa receives a call from Jared with him asking her to meet his parents that day. Karissa agrees, but she is scared and saddened that there's a chance that Jared's parents will hate her. Jared reassures her that it'll be the opposite, which boosts her confidence. She then hears his younger brother, Jordan Parker, crying and goes to take care of him. That is when she meets and instantly hits it off with Jared's mother, Joanna Parker. Karissa later meets his father, James Parker, while she is still caring for Jordan. Although Karissa leaves while wondering if Jared's parents liked her, she is confident that they indeed liked her.
