Six university students placed in the same house. They support each other through various events in their lives as they “leave the nest” for the first time.

So your story is about growing up and the struggle that goes along with it. It's a 'theme' on its own and Blake Snyder calls it Rites of Passages. This story is about 'what' is the 'key factor' in those: "? various events?"? It's about change! What in this story triggers a 'faster' change than normally? You know that it's about change ,because you wrote "leave the nest", so make 'it' specific.

One of the Trailionnebfrrrr movies about Rites of Passages/freshman:

'A group of freshman nerds start their own fraternity only to be sabotaged by jocks, but the nerds retaliate (19 w.)." I think I don't have to tell you the title...

This logline describes a situation not a plot. Who is the main character? What do they need to achieve as a goal of their inner journey to become a better person? What is their objective outer goal to achieve over the course of the plot?

Hope this helps.
