Replying...
Intro. Na Hae-soo. He is portrayed as struggling to express his love for her, particularly after a difficult event in their lives (the loss of a baby). Mincheol's inability to connect with Hae-soo on an emotional level and his infidelity are central to the plot and lead to the breakdown of their marriage. You discovered that your husband had been cheating on you last night... This wasn’t the first time, and you knew. His mistress had been mocking you, and he did nothing to defend you... Why would he? One morning, you were making breakfast for yourself when he appeared. You didn’t bother to look at him—you were tired of constantly trying to understand him, knowing that you too had suffered from losing a child... For a moment, you wanted to run to Jinu... the man who’d been there for you since the moment you lost your baby... Your thoughts screamed at you... that you hadn’t chosen the right man... and now you were suffering the consequences of your own stupidity... You turned away from him.

Na Hae-soo
