As a secretary of one of the most influential men in the world, Grace had to look into the background of everyone who was close to her boss. Sometimes it extends to the people with whom her boss's friends and family hang out.
Her boss was a man who looked and behaved nonchalantly to the world. But only people close to him knew how protective and cruel he could get. As one of the wealthiest men chasing his elder brother in the ranking, he definitely had more than two faces.
Her boss, the fourth master, regarded his brother's best friend, Lee Whan as his brother. So she dug up details of Celestials to see if anyone would be a threat to Lee Whan or his arrogant brother Lee Yong.
When none of them were problematic, she just let them be. She did not even give a formal report, but she did speak of them and her investigation to him in passing.
Her boss did not react much to the information but teased her for abusing her powers in his name.
Lee Whan's friends call him Berry. So I will use Lee Whan and Berry interchangeably based on the situation. As for the reason why Berry - it will be revealed later. :D
