There are only two chapters translated as of now, but this manga really seems to be promising.
First of all, the main character is a manipulating highschooler who puts on a fake personnality through his everyday life, making himself appear kind and becoming popular. He really does well as main character, and is rather cunning and interesting.
His love interest is however the complete opposite of him, being closer to a (psychopatic) Mary Sue than a liar. The character sees her as his rival, but he also shows pure sentiments of love, and so we get a strong female character he'll have to win over.
But it doesn't stop here, because the real plot is about saving the world : it starts off comically, with a messiah having to accomplish perverted missions to save the world, to a more dramatic situation, where the main character is left alone, and there we lose the secondary and comical protagonist, a perverted old man.
Overall, it shows huge potential for a comical series ( the author has already shown his talent through Shiinake no Hitobito and is very original, but it could also introduce more serious games and become even greater.
