Falling in love with the taste of your lemon, love hits my brain for 0.1 Second; leaving your warm embrace, it only takes 1 second; silently saying 'goodbye' to you in my heart, a long coda plus two lines of silent tears, it takes 30 seconds; then, how long will it take to stop hallucinating that you are still with me all the time? ; Finally, if we completely forget you and our love, will it last forever?
