Always in my heart - Larry Stylinson (in progress)

The ten year reunion is on its way, and the boys have been planning it for quite a while. Tension between them gets rough after they're forced to meet up in London, and get trapped in their hotel due to a power outage. Louis, who had been going through a rough patch with Eleanor, is finally single again, making the fans and media lose their minds. So many things have changed between the 5 boys, but will Harry and Louis be able to avoid the tension, and open up to eachother again?

(so I came up with this idea really quickly and it's not very thought out, I'm hoping it'll work out a little bit, I don't really know what I'm doing so please don't hate me.
always in my heart,
yours truly,
(not) louis)
