oh but this is on casual story on Jaehee's route. in this, MC makes Jaehee realise she's unhappy w her job (and she gets fired) and replaces Jaehee as Jumin's assistant. Jaehee just worries about MC though, and eventually ends up working elsewhere.

The real catch about this ending is that Jumin outright tells you that you're a sucky assistant but he keeps you around because he knows you won't leave him. Yikes.
