The focus of this drama is not on the romance, it's more about the comics, the aliens, and the adventure. They smooshed in the leads exploring romance literally in the last few episodes just so we'd all be crying at the parting.

The ending was really a what the heck moment . I'm not sorry I watched it. I gave it a generous 7.5 just because I happen to like sci-fi and I don't think there are enough of that in c-dramas. I'd love to see this more fleshed out and to see a second season but I'm not holding my breath.

The music was really what works for this drama and I'm surprised that it got so many touching song moments in one series.
