I took 0.5 out of the overall score because the ending felt too rushed! I wish there could be just one more EP to wrap things up properly.

Highly recommended to those who are immune to cliché and old-school plot.
Extra highly recommended to those who are into lovers-to-enemies-to-lovers(again) trope.

OSTs superb.
Casts surprisingly good. Chemistry off the chart. I'm a fan of both leads now.
No annoying love triangle.

Happy ending - could still use one more EP for an 'epilogue'
