My Exclusive Tower Guide Manhwa

[Which guide will you use?] A mysterious message came to me the same day the end of the world befell us and a survival game began.
A tower that makes humans distrust one another, instigates fights, and leads humanity to destruction…
I will not be shaken.
I will see this to the end with the people I trust. …Yes, I will create a happy ending with them all!
