There's no romance in the novel but it's still ongoing, so that could change, although I really doubt it since that would erase the main theme. The novel didn't have a romance tag either, but the manga has.
Most likely going to end up with katarina i think, the musician lady, no romance is needed if they enjoy each others company. Might be the perfect thing to make him happy as she wants her free time etc as well
