“Wah~ Our ELF will really look like fairies~” Donghae said swinging the new light stick as he twirled around in tiptoes, admiring the glow the rod emitted. 
Everyone just stared at him wondering how much longer it would take before Donghae breaks it. 
All of a sudden, Hyukjae burst into laughter. “You look like a caveman swinging a wooden club!”
He narrowed his eyes, at Hyukjae's rather rude statement. “What did you say?”
Hyukjae only sniggered, seeing how much Donghae tried to look threatening.
Donghae started beating Hyukjae with the light stick, it's light switching on and off, flashing, glowing every time it came in contact with Hyukjae. 
The others only laughed saying it was now proven to be ‘Donghae Proof’. 
Hyukjae hissed in pain and regret. “You’re no fairy! You’re a frickin' FIGHTER!”
