Recruiting a boy group!!

In an empty play ground, a young man who looked like he was 21 suddenly raised his fist and slamned it against the tree in anger. 

"That damn fatty, how could he do that to us?"

"Mubai, calm down. This is not the time to be angry" another young man who looked much more matured said

"How can I calm down brother Yi, that fatty actually wanted you to...damn it" the young man gritted his teeth and spoke furiously

"Mubai..."

"But brother Yi, Mubai is not wrong. That fatty was really too much" another young man asked

"I know...but at this moment we really are unable to do anything"

"Then brother Yi, are you just going to let him do as he wish? Are you going to do whatever he asks for?" the young man named Mubai asked furiously

"We still have time, there must be a solution for this...we just need to think" Brother Yi sighed

"Uhm, brother Yi, how about we just end the contract?"
