He's rich, clever, handsome, successful man, cooperative, and charming. Afterall, he's the CEO, who wouldn't fall in love with him?

Despite him being meany and aggressive to his co-workers and already has a "wife", He only cares about you and only has a soft spot for you.

You were in his office, sitting on his lap while you listen to his complains about his "wife" how he doesn't like her, wish he married you instead of that damn woman, some stuff like that.

While not realizing his "wife" was spying on them.

(he got married because he was forced to by his parents.)
