Have you ever had this feeling toward someone when you can't wait to see him/her and when you do it's like every part of your body shakes and you feel your losing your breath, your puso beats like crazy and you suddenly feel so hot, every cell of your body calls that persons name, and you feel like you're ready to do anything that person asks you to do .. you'd even sacrifice your life for him/her, when that person becomes the reason why you're alive, and you think of him/her before every action, and nothing would make you happy madami than seeing that person happy
That's called pag-ibig .. and tell you what, I've never fell in pag-ibig :3
