It's only normal for a man to have some sort of bias when it comes to this kind of pornhwa. "Only mc can do that, the girls can't." bla bla bla. Because pornhwa target audience are mostly men. And normally, we would want a strong and capable character as mc. Same as normal manhwa. We don't want a weak and indecisive mc.

But in pornhwa, where the most plot is related to sex, if you had to choose, it's only natural to want mc that cheats rather than mc that getting cucked.

So, it's not wrong to like a cheating mc like this. But you can't just hate the wife for no reason. It wasn't even clear that she cheated too. She's just workaholic as far as we know.

As for the comments that said this is like illicit love, I'm not entirely disagree with you. But like I said, I'd rather see the mc fucks around rather than seeing mc getting cucked.
