THE DIFFERENCE BETWEEN HYEN AND HAERIN VS THE OTHER THREE

Knetz are speculating that the difference is that only Haerin and Hyein have formally returned to ADOR, having agreed to an amended contract - likely an extension to account for the period of loss/inactivity - while the other three have merely expressed an intention to return.

Even if newjeans go back to ADOR, that doesn't immediately annull the damages claims for things like complexcon, so it's believed Hyein and Haerin negotiated forgiveness for these penalties with ADOR, while the other three have yet to do so.
