Honestly id read most of my library if it didnt all go premium ; Think I have like 3 novels that arnt premium and im currently not reading them because I caught up and got tired of reading a chapter a day-week or whatever their upload speed was.
Kinda sucks having to pay or GTFO but even Advertisement revenue doesnt satisfy Qidian's endless greed. So think im done on this bottomless money pit site ;

But in the end, as a writer you have to figure out how to write 2+ characters that have enough character to make readers go "I can relate, even if I want to stab the damn characters" then make them relate to the type of love or romance you are writing (or just write really damn good so everyone can atleast say its well written).
For reference, I didnt read crap on either link, im just giving a copout reply cause I need to go and didnt want to say nothing!
The translator got fired or died, the new one hasnt posted a chapter in over a week (its been almost a month since last release) and im really curious why this book seems to be uncared for by QI.
Its a good book, give it a read.
