Looking back, nothingness; looking far away, nothingness
The scars behind the smile, the weakness behind the strength, the weakness behind the strength
A light smile can easily hurt; a bitter smile can be difficult to understand
fragile, glass; difficult to understand, complex
After the strong wind, the waves are rough; after the breeze, the lake is rippled
The risk of death, the danger of success
Close your eyes and sleep lightly, open your eyes to get in danger
Like the softness of spring, the enthusiasm of summer, the maturity and restraint of autumn, the cruelty and determination of the east
Everything - caused by the wind
