thank God for all the supporting cast and the FL! otherwise I would have stopped watching. as it was I fast forwarded every scene when the ML was alone. I have never seen a more morose, self absorbed, and ultimately odious character in any K-drama. and the "explanation" at the end was lame. all imho of course. many others disagree with me. vive la difference! and as I mentioned, worth a watch as every other character was great, and fast forward on Netflix is fantastic. btw, no problems with the lead actor. the writing was the problem.
