When Ami threatens Jin-Ho because she knows about him and their teacher, due to her aunt divuandging that Information to her, why doesnt Jin-Ho bring up the point that if Ami tells anyone about his current situation, then he will go after her aunt for breaking possibly the most important rule in her field. Ami threatens Jin-ho with expulsion and thier teacher with being fired, but the consequences facing Ami's aunt would be far worse than that.

BUT, then again, if Jin-Ho had done that, we wouldnt have gotten the chance to see how silly and Immature Ami really was when she goes all yuri on their teacher. Silly girl either way you look at it

I am eager to hear other thought on this matter.

Well if logic can be made then drama series wouldn't be drama series, lol. Pretty sure most (if not all) drama in any country has some kind of loop hole that viewers would just accept because it'll continue the series' tension.
