I can't tell you why I read this far. Here's how I imagine this series got created.

Author: What's the most formulaic way to make a popular manga. Let's take another androgynous lead and make a bunch of archetypical girls to form his harem! Wait we need another hook. Screw it, throw in some music and talk about climbing to the heavens or some bullshit. Wait we need Drama and angst! Let's kill off a character early in! That'll show that I'm edgy and anything can happen.

Seriously the art isn't anything special and is filled with fan service to keep 13 year old boys happy. The storyline is poor with only a few real twists and mostly focuses on the girls falling for this one moronic lead (who sucks but more on that in a sec). Now my real gripe with this story, The Characters.

If you aren't into the harem Genre this will have nothing for you. The characters don't really have any depths to them besides the superficial amount they mean to the main character. All of the girls in the series have one or two main characteristics and, shockingly, are in love with the MC. The few guys in the series are the same thing minus the loving the MC.
The one that really cements this for me is the Main Character. He is cheesy, wimpy, and a bit annoying. Now he turns out to be a giant hypocrite. I don't know why I was even a little surprised. SPOILER warning: I don't know how the hell an author could kill off the main character's girlfriend then bring in a girl that could be her clone in as the true love interest WITH THE SAME NAME as the former girlfriend. It is seriously like he was trying to troll his readers. Guess what, you succeeded and I hate you for it.

TLDR: If it looks like poop and smells like poop, its poop.
