Since studying to be a scribe is quite expensive, the Cassia family purposely offered to sponsor young individuals with talent generously until these young men and women were blinded by their so-called kindness. Eventually, when their guards were down and right before they completed their education, they were tricked into signing unethical contracts that will technically make them slaves to the family as a means to pay the "kindness" shown to them when they had nothing.
The sponsorship that these young individuals thought was free was actually only a trap to emotionally blackmail them in the future. It was actually a carefully packaged debt contract turning them into slaves for the Cassia family. All the things that was originally sponsored to them will then have to be paid through labor for several years written in very fine print.
