The Captain's Girlfriend Is Ghost Hunting Again

A Ke is troubled because she has a boyfriend, and he always acts up when she's out catching ghosts.

A certain group leader is also troubled because he has a girlfriend, and she always goes ghost-hunting when he wants to kiss and cuddle.

The female lead is cool, aloof, domineering, and strong (against nonhumans). She's not the flirty type. Don't read if that's not your thing.
