Review Detail of wncrystal in The Legendary Actor

I have read for about 900 chapters. But I'm really not sure whether to continue or read later. Till the chapter i was reading, i loved every bit, but i was dumbfounded when Heather Cross died. I thought she was the love interest even though some clues suggest she might not be. Can anyone please tell me who is the love interest? According to some reviews, they said that till EGOT was pretty good but after that it went downhill. I really love Renly's character and personality so i am hesitating to continue because some readers said that his character collapses. Although I know that i should read it myself and decide because different readers have different perspectives, I really don't want to take risk as i love his character so much. I hope to get some help. Thank you.
