to me, mincheol is your classic narcissist.
He first, set his eyes on haesoo and acted as she liked/would develop a good opinion of him (masking your true intentions fase)
then, he started doing all this over the top things for her, looking for her, getting her gifts (love bombing fase)
once she was drown into him enough to marry him, he started to be his true self day by day (mask down fase)
now, he cheated, robbed her, took everything she was and dumped into the trash, yet she's the one in the wrong (you'll be the villain no matter what fase)
