At first it was interesting since the plot revolves around the female lead that's already dead, i do say they're bold to kills of best girl of the series, but the other characters were getting boring and the action scene was bad.
The other female characters were playing with detective roles as if it's not serious job, and ngl, the male mc is dissapointing. He's not skilled in combats, hence the detective that's already dead pretty much took care of him, a feelers that's just... Getting into my nerves, have deductions skills only at the beginning, can't predict future possibility, overall his bad looks shown after "the detective" died. Ofc he's just an assistant, but he's not reliable, only his talent at attracting enemies is what he's good of.
