Strength comes from many places.  

It can come from the people around you, life experiences, it can be forced on you, or it can sometimes come from all things combined.  Sometimes it's blatantly apparent, and sometimes the layers of grime that life can cover us with has to be brushed away first.  But wherever it comes from, or how easily it is or isn't seen, strength makes us dazzle and shine from the inside out.

But there is a very fine, blurry line between strength and stubborn pride.

Key and Taemin are both strong people, but in vastly different ways and through vastly different means.  They are together via unfortunate circumstances, their different types of strength sometimes causing tension, but ultimately fostering a strong bond.

Then comes Minho and Jonghyun, who will put Key and Taemin's individual and combined strengths to the test.
