How to Conquer the Tower of the 'Hanamja'

I actually read this as a novel, and recently it started being serialized on Naver Webtoon. Roughly, the plot is: They call him a 'Hanamja' (a term for a man lacking charisma or appeal), but reading the novel, I don't really see the protagonist as one. Anyway, the story is about the protagonist Bong Ju-hyeok, an ordinary 'Hanamja' citizen, who suddenly awakens as a player while eating ramen and climbs a tower. His special ability was something like 'Dimension Summoner', right? Unlike other jobs that control monsters, this protagonist summons people from other worlds. Each of those characters is unique, and the plot unfolds satisfyingly, so I recommend it. Ah, I got sidetracked. To continue the plot summary, the people summoned are called 'Summoned Ones', and these Summoned Ones are incredibly strong. He climbs the tower with those strong Summoned Ones? Destroys the creator of the Black Tower, the 'main base Earth' (No. 1)? In the side stories, you get to see the stories of those Summoned Ones too. That's the kind of novel it is. The webtoon seems to have about 50 episodes out now? Admittedly, as the novel had illustrations, 'Rajix' came out exactly as I imagined, but 'Veronica' is very different from how I pictured her. Anyway, highly recommended!
