This series was a lucky find for me. I usually go down lists of mangas, trying out each one, and I happened to come across this one. The description initially kinda threw me off since it was so weird and new, I mean, what did it mean by spam? So I gave it a shot since I had nothing else to read, and I ended up staying up all night finishing it one shot.
And wow, seriously give this manhwa a chance if you are into action, shoujo, scifi, bishies, or just need something new. The plot line is enough to keep you going since it
diverges from the boring clique shoujos, and since its sci fi, it's cool to see futuristic problems that they face that we may come to realize as well. As for the art, it's similar to that of Gong, but you could also see that the author put a lot of time and detail into it (esp. into the hot male protagonists ^_^). The characters are well developed and unique and the heroine actually doesn't make me cringe or want to throw something against the wall.
Anyways, once again, I highly recommend this manhwa to all you so try reading it! :)
