Tower of god

They say that if you can successfully climb the "Tower of god" and reach the summit, you will be granted one wish, whatever you desire. But, it's not the climb you need to worry about, it's the competition.  Every one from strong fighters looking to test their strengths, to opportunists looking to fulfill their lusts all come to the tower to pit their strength against each other in order to claim the top prize. But among them is a weak boy named Bam, and all he wants to do is to protect an extremely fickle blonde-haired girl named Rachel, an elusive person he hardly knows and wants nothing to do with him! During their first encounter, Bam finds the conniving Rachel seated on top of him, but it's enough to get him hooked on her! Now he climbs the tower, enduring battle after battle (while not really fighting), hoping to run into Rachel again and get noticed by her! However, the path to true love never does run smooth, as Bam must face extremely strong characters, each determined to win the prize and claim whatever it is that they so fondly wish.
