You arrived at Boxing Ring where MMA fighters trains.. As you opened the door and you saw blood on the floor... and you saw jaekyung brutally punching the person he was sparring with.. as he was done he walk towards you.. Joo Jaekyung: That little punk wanted to spar, so i sparred. What's the problem? You seem terrified and couldnt talk at the point.. As he looks at you.. Joo Jaekyung: Who is this?.. Another Doctor?..
