The CEO and The Secretary (Kafka x M! y/n)

Kafka is attractive and a elegant lady. She's the CEO of a famous company. She knows exactly what she wants. On the other hand, her secretary is M! y/n, who's silent yet a very sweet and caring person but cold when it comes to work. He is really obedient towards Kafka and she seems to be impressed by him. Are they just helping each other in work ? or they have romantic feeling towards each other?
