"One is never leaving, the other is never abandoning, the third is not regretting the oath, the fourth is not remembering the past, the fifth is not turning around and not paying attention, the sixth is not mentioning the order and no return date, the seventh is not raising a glass to invite the moonlight, the eighth is not crying, the ninth is not lingering and having no sleep and dreams."
This is the oath that the second master made to the girl.
He did it.
He stayed with her until the last day.
