On the 17th of April, the developers have expanded The Sims Mobile by two new relationships stories. Thus far, you could only have stories with random sims, but these new stories change that. In order to start a relation, you have to choose the right sim.
These stories also add new events. Now, apart from meetings at home, you can also take your partner to the city - for a coffee, etc.
Sibling Rivalry is a story that begins with the "rival" interaction. This relation can only happen between siblings, quite obviously. The age of the sim isn't important, nor is the fact if the sims do live together. The story unlocks two pieces of clothing.
Better Late than Never
Better Late than Never is a story about searching for an old love of your friend. As the relationships develop, you'll be able to learn what happened - how was the love lost and how is it going to be reclaimed. This story begins by "friend" interactions. The story can only be carried out by a senior, regardless if it's your sim's family. The story unlocks two outfits.
