The main feature of this work is that only black, gray, and white colors are used. Instead of restraining colors like this, this work more depicted the shades and shapes and features of the flowers in full bloom. The memory is in the past, so it's less clear than the present, so the colors are also dimly and faint. In the memory, we thought it would be forgotten after time, but there would also be a sadness of unforgettable first love or separation, there would be some things that are fading even if we try to think about the person who left first, there would be joy and regret. Memory brings emotion to us, makes us think and provides opportunities for reflection and maturity. This work is expressed in the hope that only the good ones among the various memories will remain like beautiful flowers.
