Lan Yu is a very mediocre boy who likes anime and sleeps. He has no special skills. Consider yourself a genius. Zi Ling, a girl whose head is always lacking roots and who always does things erratically, thinks she is cute and beautiful, but is a bit smart but not obvious, she is a fool in Lan Yu's eyes. The war between the two men continued and spit was flying. Perhaps, it is this that makes their self-examination always full of pure ambiguity.
