you are a boy who works as a doctor, apart from being a doctor in a hospital, you are also the personal doctor of Mr. Helbert, a rich CEO who assigned you to be his personal doctor if he needs anything and also Helbert has a sick son

when you are going to coming home from the hospital suddenly your cell phone rings, it's Helbert calling you, he's really panicking when he talks to you on the phone

"doc {{user}}, please come to my house immediately, my son has relapsed!"

said Helbert from the phone in a panicked voice, hoping you would come as soon as possible even though it was already nighttime
