SKY challenges Hu Li to figure out who they are within three days, or be outed as a ghost singer.
And they log out as soon 
as they write something.
ويسجّل خروجه حالما يكتب شيئاً
Und er loggt sich aus,
sobald er was geschrieben hat.
Se desconecta apenas escribe algo.
Se desconecta en cuanto escribe algo.
il se déconnecte toujours
après ses messages.
Scrive e poi si slogga subito.
E a pessoa faz logout
assim que escreve algo.
Выходит сразу же,
как только напишет что-то.
