In midair, Shang Jianyao stretched his arms as if he were a giant bird in flight. He didn't mind that he would really fall to his death from being 'pushed' off the rooftop for no reason. He was abnormally certain with a heart of steel.
Genava—who was originally worried that Shang Jianyao's scream would attract attention—had already stretched out his left hand and planned on covering his mouth. He also sighed with emotion in the main chip.
Even if he was 'acting,' it couldn't hide the fact that Hey was a mental patient!
With Shang Jianyao's cooperation and Genava's meticulous selection of lesson time and a relatively hidden corner, the two of them didn't attract anyone's attention as they 'proceeded' down.
In such a surreal scene, Genava didn't want to attract the attention of others because of Shang Jianyao's 'jump' and 'flight.' This might very well bring about an unknown and dangerous accident.
