Emotion is your answer!
Hint: Love means knowing that no matter what, you have someone to count on. It's unconditional and makes you feel good on the inside. You can trust the person you love and are comfortable around them. It's like your heart tells you that it is good for you. Love never hurts or makes you cry your eyes out.
So therefore your answer is emotion, have a good day or night! Stay positive
