Does it make sense to travel across the multiverse for a man who doesn't like you back?

So what things are left to explain?
>Why is GQuuX apparently alive
>What is Haro
>Who texted Machu
>Shuuji's connection to Lalah and who he is in the OG universe
>Devil Gundam
>Kycilia and Char/Chalia's beef
I don't want to have to wait for the movie to get the answers
