DID FINISH THE DRAMA! I RATE IT 8/10 . ABOUT THE ENDING, DID THEY BOTH MEET ON DIFFERENT REALITY OR TIMELINE. OR THEY ALL JUST STUCK IN A NEW LOOP, WHERE THEY SACRIFICE THEMSELVES AND WATCH THE NEW TYPE OF SIGMA TO ARRISE AFTER RECIEVING THE NOTE BOOK IN REGARDS ABOUT THE THINGS HAPPEN IN THE PAST SUPER CONFUSE ABOUT THAT PART. IM STARTING TO REALIZE THAT THEY ALREADY CHANGE THE REALITY WHERE SIGMA ON THAT REALITY HAVEN'T SUCCESFULLY INITIATED A WAR BUT NOW SEEING THE NEW SIGMA GUY. DOES HE HAS A NEW PERSON TO CONTROL? LIKE THE GUY ON THE FORBES MAGAZINE ... GUSH I DO HOPE HAN TAE SUL AND SEO HAE BEEN TOGETHER ON OTHER REALITY. AAHHH GUSH EXPLAIN TO ME I'M OUT OF BRAINCELLS :C
