As said before- the characters of LUST are not perfect, they have their own flaws and weaknesses. It might be love or lust for one other. But it's your choice if you wish you read this or not.
Warning: THE CHARACTERS ARE NOT PERFECT AND ARE TOXIC TOO!!
I won't try to spoil the story saying the matter, but if you wait and read patiently you'll understand everything. The next chapter will be TAEHYUNG'S POV entirely. Neither I'm forcing anyone to read, it's ur wish and I respect that. This was what I meant by in the Disclaimer at the start of the book. The love is only for Tae by Ava, he only cares for her and looks her as his friend, only with a little attachment. His heart still yearns for Jisoo. This is all I can say.
