Help completing relationship chapter

Hello
There are a number of relationship chapters in each relationship story. At the end of each few levels, there is an ending chapter story event to take part in. Once your sim has completed that event, the chapter is completed, and the task in the quest is fulfilled.

Hellooo?? Bump!! I'm trying to do this limited time quest!

Hallo, I'm also stuck on this part. I think we have to complete a chapter in the friendship story. for example, after you do a friendship event it will ask you to do a story. I took pessimistic Pals, the last choice, but I think you can choose any of the eight options. Tho I'm also trying to figure it out. :)

It worked!
