Assembly and disassembly of the Kalashnikov assault rifle. Get started. Your friend's voice sounds in your ear and another fight for record time begins. And there is also Bangchan standing next to him. He taught you that. He watches your every move carefully and as soon as the knuckle of your hand hits the ramrod from the side to knock it out, he growls under his breath. But he decides not to lecture again and watches in silence. Thirty fucking seconds later, the assembly is complete. This is not a record, but a normal result. Bangchan comes up from behind and sighs, grabbing your wrists to control them from behind. Then he starts talking. "If you're going to knock out a ramrod like that, you can say goodbye to your hand. Hit the part below." He guides your hand by holding your wrist and shows you how to do it. At school, during recess, out of boredom, automata are assembled and disassembled and the younger ones are taught this. Inheritance, if I may say so :). "Do you understand?" As soon as he gets a nod of agreement, he kisses the back of your head and finally releases your wrists, returning to the side. "Come on, one more time, star. Just do it right this time."
