I see some of you expressing concern about the “morality” of the ML’s actions, and I get why it might feel uncomfortable at first; I felt the same way initially. But after looking closely at the context, I don’t think there’s anything morally wrong. Here’s why:
Curiosity over romance at first: In the early episodes, it doesn’t feel like he’s romantically interested. His brother has passed away, and he doesn’t know the full circumstances, so seeing his sister-in-law naturally sparks curiosity. He’s trying to understand what happened and make sense of his brother’s life and death. That explains why his attention is focused on her initially, rather than being driven by desire. When FL saves him from a deadly accident, his concern grows, but still out of care, not any inappropriate intent. Also, they never shared any kisses or intimate scenes before he learned the full truth, and her teasing him in the early episodes felt like her way of keeping him at a safe distance while he was always tiptoeing around her, thinking maybe that this provocative behaviour might make him uncomfortable and eventually make him less interested in her.
Caring gestures are empathetic, not manipulative: Some viewers point out that he tries to touch her frequently, which can feel uncomfortable. But context matters: these touches happen after he sees how badly she’s been hurt physically and emotionally, and because she saved him. He shows genuine concern, protectiveness, and gratitude. He's not about crossing boundaries or personal gain; he reflects empathy and human compassion.
No betrayal or wrongdoing: The ML never betrays his brother, and the FL isn’t being unfaithful since her first husband is dead. Developing feelings for her late husband’s younger brother, whom she barely knows and is essentially a stranger, is not morally wrong. Any perceived “gray area” comes from societal or cultural perceptions, not actual ethics. Evaluated strictly on morality, consent, and care, their relationship is fully consensual and founded on genuine mutual concern.
The bigger context matters: They got married while he was abroad, so they hadn’t even met or seen each other’s photos at the time. His brother and sister-in-law married quickly, and the drama immediately jumps three years ahead, focusing on FL’s return for revenge. The story gives almost no insight into their early married life, so judging morality based on that limited window is misleading.
Humanizing and relatable: Watching him respond to her suffering with care and empathy made his actions feel human and believable. It shows a person trying to do the right thing in a complicated situation, which helped me move past the initial awkwardness.
While it’s natural to feel awkward at first, when you consider the context, intention, and ethics involved, there’s nothing morally wrong.
[This is just my personal opinion and in no way a general statement; everyone can view it differently. It’s ultimately about perspective and understanding the reasoning behind the characters’ actions.]
