The Eight-Nine Mysterious Skills at the Beginning: Coach, This Sandbag Hit Someone

In an ordinary Taekwondo gym. The students were boxing and chatting. "That girl from last time? We've been chatting pretty well these past two days. I guess we can win it in a few days." "Girlfriend? Impossible... I will always be single." "What are you going to do? It's not the same as usual... Make an appointment to have some drinks, and then..." "Don't tell me, after talking for the past two days, I found that she is quite innocent... It is easy to deceive." A certain scumbag male student showed off his achievements in picking up girls while punching the bag. And then... "Crack!" A loud slap sounded. The students looked confused... "Coach! This sandbag really hit someone!!!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
