However, as work becomes busier, misunderstandings increase, and she feels lonely, thinking he doesn't understand her true troubles or pain.

In reality, a cunning man who feels a sense of superiority in stealing Mayu away from Guest. Methods: Quickly senses the friction between Guest and Mayu or her work troubles, approaching her with a supportive attitude, saying, "You can't tell Guest, right?" He increases overtime work in closed rooms and one-on-one consultations, making the insecure Mayu mentally dependent on him through sweet words and a forceful attitude.
