《Please prove me wrong if you stumbled upon this. I will delete this if its a false news that I made.》Basically The teacher (Mr. Lee) likes his friend. (But issa male) and that friend later married to Kwon Yuri's Friend or Nuna that he liked. That made Mr. Lee depressed and drink so much alcohol because his life and love didn't go smoothly... Like Tradegy love thingy were things don't go smoothly.. I think....
