Nope. The ending was quite lacking.
Spoilers!!!!
The novel ends with Woojin winning a Grammy award and him dating Miley heavily
Spoiler Continuation:
He was excited for his future acting roles but was anxious about how his persona would affect his future especially now that he's in a relationship. So he decided to tell Miley the truth about his real self. But Miley thought he was joking and didn't believe him.. so ig it's an open ending with Woojin never escaping his nonchalant genius persona.
That's it?? thanks for telling
he can't open the void and lost all his acting skills and he'll be forced to act on his own and then he realizes he doesn't need it anymore and boom, the end.
