I can't find this comic

I can't find a comic that I really liked that I believe I read on Webtoon. I was hoping someone could guess what it is. I also have a screenshot of it.

The main character has restoration powers. We see him rebuild a building that was once crumbling. Apparently people in his world are hired to do similar stuff. There are dungeons on earth that suddenly appear and destroy the things around them. So factions/teams of people with powers are hired to stop them. They appear in dungeon type forms with monsters to fight and they're could be a time limit to beat them but I don't remember. All dungeons level on skill, but when alarmingly bad ones happen the world sends their strongest group. The main chat was amazing at restoring so when this guy hires him to join his team, you realize that the main character is the newest addition the most popular team in the world who fights the hardest dungeons.

You also learn that the main character is living with his old friend/team mates who all died. They now are kind of like zombies, and the main character has tried to kill them in any way possible so that they can rest but hasn't been able too. One of the reasons the main character joins the hardest team is because the leader (the guy who hired him) has the ability to kill his friends with his dark shadow type powers.

The main character fights in the dungeons with his new teams and it is very hard for all members. I can't remember exactly but I believe that each dungeon appeared at the 7 wonders of the world. The main character trains his restoration powers, and learns to mid-fight restore.

The world has amazing media coverage of the dungeons fights and pressures the main character a lot. So much so the that the leader guy takes his phone at one point maybe I haven't read this in a while.

This could also be a romance I don't remember. But it would be between the main character and the leader of the team.
