“Hey, have you ever heard of the lunatic roaming around the tower?”“Are you kidding me? Who haven't heard of him yet!?”“Hey hey, are you talking about... that person?”Interesting news travels even faster than light, especially regarding the mysterious figure that everyone in the Ethereal Tower is curious about, the lunatic ascender whom thoughts and deeds are so off-place that even the greatest among them just couldn't grasp his intent, almost as if he is ascending a completely different tower than them.While everyone in the tower talks about the lunatic who lurks on each tower's floor more than he is supposed to, the person they are talking about just goes on his merry way to collecting treasures he wants, and while the world is talking about him.“Come on, give me some luck, maybe roll the hundred times multiplier again...”He's sitting while rubbing his palm together, gambling on something that will make everyone faint.

College was like a wake-up call for most people. Especially the likes of Christopher Owen, who spent the rest of his high school years messing around and pining for the boy he never had.Having had a frustrating high school year, he decided to dedicate himself to his studies in college.He flew many miles away from home, changed his looks, and hid his real identity from everyone. His plans were simple: study hard, pass well, no dating.But then he realized two things: life was anything but easy without the backing of his last name.And... he wasn't sure how long he could last before he jumped his roommate, who was obviously not gay.But lust wasn't love, right?Maybe he could indulge a little? Just a little, I promise.
