As we known, the light is a metaphor, there isn’t such thing in our everyday life. But the mundane prejudice exists for quite a long time. No one can perfectly define the love, no one can identify the intimate or distant degree in a relationship/marriage, no one can entirely understand his/her spouse’s mind, no one can judge who is loved or unloved. We may ignore our spouses for years like Wu Wenxue (acted by Huang Bo), we may pursue the diverse opposite sex to search ourselves like Li Nan (acted by Wang Luodan)’s husband, we may deny the homosexual tendency like Chopsticks (acted by Bai Ke), we may hurt ourselves (even jump off) to show our love, we may fall into a vague emotion when comes the adolescence. Therefore, are we luckier by going with the light or remaining in this world? The answer is yours.
