1. "认为生命中最重要的、不能失去的男人要求毒誓" - i don't think it's "自然而然". when a woman truly loves a man, most likely she respects him very much.

and if i respect someone, i'll never ask him to do that.

2. 阿朱开始还象一般的女人，后来越来越象圣女 - that's exactly what i'm saying. true love changes a person in an unspeakable way.

3. 杨过对 N 个女孩动心, so i guess only 立誓 works for someone like that, 油滑，饶舌、多话 ....

4. "这种对感情的信心、坚定太凤毛麟角了。" - r u kidding? 立那样的誓还叫对感情有信心?

5. keep 暇想. hahahaha~
