There will be more images featuring Jesse in the next update, yet! No new written content, as we need to catch up on visual assets for his routes (and there will be additional routes for him to be deployed in the future).
Nothing more for Bruno in the next update (we're caught up on where we need to be for his content at the moment, although we'll be developing his full routes in the future, which you'll see in later updates).
However, the V0.5.5 update will feature a fully brand new route focused on another character, so keep an eye out for that ;)
