It's been a few years since I read it but one of the bigger selling points is the art is amazing, it was a silly fun time with a fairly unique premise for a manhwa. The basic premise is in a world with magic this one girl uses a summoning spell for the first time and summons a NEET from our world. It turns out this NEET is incredibly powerful when summoned and they go on an adventure to save the magical world (a few times? IDR). And there's a good amount of character growth as the story progresses. It's only 117 chapters so pretty short as far as manhwa goes.
