Flowers, as the inner, HER. Leaves, as the exterior, HIM. The sunshine makes HER feel warm. The brightness makes HER feel comfortable. When SHE is well satisfied, basically it is a good work. This work, makes HIM feel well supported, and willing to devote himself while enjoying being with HER. When it’s not a sunny day, HE is on duty to organize this work, in the alternative way. By co-working with each other, SHE/HE gets stronger, than what they originally were.
