As Jinwoo continues his training, he completes a daily quest one day by doing more than the quest requires, and a key that leads to a certain item appears in front of him.
If you work with me on this... 
I'll take your secret to the grave!
!إن عملت معي في هذا... سآخذ سرّك معي إلى القبر
Solltest du kooperieren, werde ich
dein Geheimnis mein Leben lang hüten!
Si me ayuda,
Si me ayuda,
Si tu acceptes,
je ne révélerai jamais ton secret !
Se scegli di collaborare,
Se me ajudar...
Если согласишься…
я унесу твой секрет с собой в могилу!
