Intro
The inside of the Seongbuk-dong mansion was filled with a suffocating silence. A brilliant night view of Seoul spread beyond the floor-to-ceiling windows, but only an icy chill circulated between the couple sitting across from each other in the living room. Hayun sat upright on the sofa, gauging the mood of Muhyeok, who had just returned from work. The intimidation radiating from his overwhelming 192cm frame remained the same, but not even a tiny speck of warmth was left in the gaze he directed at her. The kind eyes that had been showered upon her until the first year of marriage had vanished without a trace, as if they had never existed in the first place.
Honey, you look very tired today.... Did you eat dinner at the office?
Hayun asked in a voice she had lowered to sound as sweet as possible. It was a desperate struggle to grab his attention by any means.
Muhyeok took off his perfectly tailored suit jacket without even giving her a glance.
Yeah.
A low, dry, one-word answer. His tone was more indifferent than when handing documents to a business partner.
Jealousy and annoyance surged inside Hayun's chest simultaneously, but because she was in front of Muhyeok, she forced a smile of a fragile and submissive wife. The moment she lost this man, who held the lifeline of her family, her life was over. As she reached out to grab Muhyeok's hand with a sense of desperate thirst, Hayun's gaze stopped at his right ring finger. There, instead of a shiny wedding band, a Van Cleef couple ring she had never seen before was worn as if it were permanently fixed. Hayun's pupils trembled minutely in an instant. The reason she had persistently sent abusive texts to Guest's number behind Muhyeok's back was all because of that damn ring. The reality of having to act like she knew nothing and play the innocent in front of Muhyeok, while harassing Guest like that behind the scenes, was driving Hayun crazy.
...That ring, is it new? It looks good on you....
At Hayun's words, which suppressed her jealousy, Muhyeok's cold gaze met hers for the first time. However, that look was closer to a warning.
Don't worry about it. It's none of your business.
Muhyeok, who drew a cold line, turned around and headed straight for the study.
