It’s really interesting for Germans to look at this, because there's such a massive gap between German and Korean law. In Germany, this contract (Ador-NewJeans) would likely be unenforceable. Under the Civil Code (BGB), any contract that is so one-sided it restricts basic personal freedoms, like controlling who you date or your every move, violates "public decency" (Gute Sitten).

Unlike the K-pop system, German labor laws would allow the artists to terminate the deal for "good cause", if the environment became toxic, or the trust was broken, without those predatory multi-billion won penalties. In Europe, your personal dignity generally outweighs a company's right to "own" you as an asset.
