What happens?
SPOILERSS
Its a bit complicated, but sayoung ends up having to forcefully merge with another world’s Lee Sayoung, which causes him togo comatose in order for his body to maintain the two souls in one body. And during that time, i wont go into full detail, but the world gets into more chaos and J is forced to reveal himself in order to bring order back whilst sayoung recovers.
It's just a matter of time until we reach the part when Sayoung will fully sleep for days even months and J decided to show up since public was getting restless by Sayoung's absence.
