"There are trees in the mountains, and trees have branches... I feel so happy for you, but you don't know, what are you filling in?" Tao Tao was speechless.

"Originally, I am so happy that I don't know how happy I am." He smiled happily.
"... No, I won't tell you anymore." Someone ran away with his face flushed.
