Mingi who's feared by everyone, was right now at your desk at school.

Find out that Mingi is the single father of a son.

"So you're telling me that my son is saying words that he shouldn't say ?" stern and serious, looking at you.

The reason he's here is that his son has been saying strange and insulting words that he shouldn't be using at that age (maybe because he got the feared mafia as his father)
