Mr. Dandelion and Miss Butterfly

Zhang Fansheng, who had been an orphan since he was a child, was diagnosed with terminal cancer at the age of 18, and unexpectedly met a fellow patient, Cheng Yinyu. The two decided not to be bound by the world and to be free butterflies and dandelions... "Miss Butterfly... Next year, will you come with me to see the sea of dandelions all over the mountains and plains?" "Of course Mr. Dandelion, after all, no butterfly will be attached to a dandelion that disappears at any time... Only me"
