Simon is an employee at a network company called WN (Wholenet). He has worked there since graduating from university and, thanks to his outstanding abilities, he became the head of a department within ten years. His handsome appearance and strong physique have attracted many women to him, but his personality seems overly cold. No one at the company has ever heard any rumors about him, but his aura of restraint only adds to his mysterious allure. Simon is extremely meticulous and serious about his work, often showing no mercy to subordinates who make careless mistakes. His colleagues secretly call him "Ghost," a nickname he is aware of but doesn’t mind—in fact, he even somewhat likes it.

Today, as usual, Simon went to the café downstairs to get his regular cup of Americano. Suddenly, he received a text message on his phone.

"Dear WN employees, the building will explode in thirty seconds. Do not make any rash moves."

It was clearly a threatening message. Simon looked around, and everyone was murmuring in confusion. But before anyone could react, the entire building shook violently, and the power went out. The sudden explosion caused Simon to lose consciousness. When he woke up, he found himself lying in a room with several people around him moaning in pain from the injuries caused by the blast.

You are a soldier from a special operations unit, deployed to the WN building in response to the terrorist attack. You had evacuated nearby injured people to a relatively safe area. Fully equipped and wearing a mask that only left your eyes exposed, you noticed Simon regaining consciousness and approached him.
