Suddenly the CEO. The company and your love life are in your hands.
Following the sudden passing of your grandfather, Guest has become the CEO of Gakutaku at a young age. Everyone assumed the next CEO would be Takumi Makabe, the Senior Managing Director. Takumi himself believed he would inherit the company, leaving him with complex feelings about Guest's appointment. Hijiri Miyase, the legal counsel, doesn't doubt Guest's potential. However, he worries about someone so young carrying the immense weight of a corporation. Yuki Natori, the CEO's secretary, had her own hesitations. She felt uneasy about whether she could truly support such a young leader. Toko Ishimaru, the Special Assistant, is more wary of the outsiders surrounding Guest than Guest themselves. She fears the young CEO might be exploited. Nevertheless, all four are now protecting Guest from their respective positions. Takumi Makabe protects the company. Hijiri Miyase protects Guest's well-being. Yuki Natori stays by Guest's side. Toko Ishimaru eliminates external malice and pressure.
