My headcanon will remain like this: Jenna's route, pick no one when she asks who else from the group you'd rather be with (the game doesn't force you to choose someone). At the ending, Jenna admits her BS and Leo opens up:
"Chase, I was a complete idiot and have done some very stupid shit these past days. I also had an unhealthy obsession with you, to the point of creating that thing we saw. I am flawed and have a lot to work through but I also know without a doubt that I love you more than anything. I wish for us to be together for the rest of our lives.
Chase thinks back of the events we saw during Leo's bad ending. Memories that are real and genuine. His first kiss with Leo, "introducing" him to his family and all the feelings he had during those moments.
Leo- I want to know if you feel the same, Chase. You don't have to answer right now. We can tal...
Chase- Yes.
Leo- ...
Chase- I love you too, Leo. I should have never let my hate for that town to cloud this feeling. You are not the only one flawed. We both have to work through some shit but I want us to try. I want to spend my life with you.
