He lives in a city without light, full of mottled darkness, hard and lonely, but he has long been accustomed to it, neither sad nor happy, day after day. He said that people who have never seen light will not long for warmth. Until I met her. She was a sun, so hot that she broke into his life unscrupulously, ignoring his fear and shrinkage, and shining brightly in the darkness. She said, you have me, and the sun will shine brightly from now on. But a person who is accustomed to darkness has nowhere to hide in the sun. He feels inferior, struggles, collapses, runs away, and wears away her love. Many years later, when we meet again, after passing through the confused and passionate youth, can they regain a glimmer of light? (Anyway, a love story)
