H-how u'll make sure it's a girl tho.. by killing every boy and keep the girl ಠ,_」ಠ?

Y sperm tend to be faster, but have a harder time surviving in the vagina. While x sperm tend to be hardier, but are slower to fertilize the egg. So if the couple has sex a couple days before the woman ovulated the chances are higher for a girl, but if if they have sex the same day the woman ovulates it is more likely to be a boy.
Much like men with longer penises

This webtoon really on different level. It's makes me knows about how trauma deeply attached to someone to the whole new perception. I love how everything in this webtoon attached, connected to each other and leave some scars. It's so beautifully written. Even the drawing style is so calming yet it pains me sometimes to see how innocent the art is. I love everything about this.
Shit that line is killing my heart ಥ‿ಥ
