The first ending is darker than that to be honest.
The Green Haired Girl (An Princess if i do believe) when she became "Ntred" by the two guys they made her "vow" that she will only show her "affection" or something like that, to then, and when they want she will complete ignore the main character and go satisfy then! (All the other girls except by the sister is basically the same thing) But the thing is, she actually find that she wants to be controlled by then, and the ending it was an choice that the goddess gave to her heart, what she truly wanted. By the end of the story she wanted that the only ones who she truly loved exist with her, essentialy those two. But here it comes the creepy part. Not only every single man stopped existing except by those two, but as well NO other MALE baby will be borned and no one renembers about ever existing other man in the entire world. Worse than dying the protagonist is forgotten, like he never existed on the first place, as well as every single male human being on the world. Poof! They never existed...
