The next morning while Hyunwoo was getting ready to go to work, his mobile phone buzzed . Who the h.e.l.l is calling me at this early hour? Oh, it must be brother Kang Byungwon . Suddenly, Hyunwoo began to worry because his early call like this suggested something unusual happened . Whats the matter? h.e.l.lo? Mr . Jang, what the heck is this medicine? Looks like something is wrong with Mingyu . It seemed Byungwon was calling him while running, Why? Whats the matter with him? After taking the medicine, he suddenly fell down, complaining he felt dizzy . Fell down? What the heck is this medicine? asked Byungwon in a furious tone . Given that he usually didnt call Hyunwoo, Byungwons call showed how embarra.s.sed he was at the moment, but Hyunwoo was calm because he knew why Mingyu fell down . I told you already that Mingyu might feel dizzy as his const.i.tution is changed by taking the medicine . So, its nothing to worry about, said Hyunwoo . How can I stay calm when Mingyu falls down like that? rebuked Byungwon in an angry tone . Though Hyunwoo did something good for his son, he now found himself rebuked by Byungwon, but Hyunwoo could fully understand his mind . As he had only one son, it was so natural that he got enraged like that . Hyunwoo told him again in a calm tone, Thats a normal side effect, and he will wake up quite soon . So, please rest a.s.sured . However, Byungwoo was screaming at him and suddenly hung up the phone . Scratching his head, Hyunwoo murmured, I wish I had emphasized about that side effect . After a bit of agonizing, Hyunwoo sent him a text message . Byungwon was absent-minded . He took him to an emergency room and pressed on the duty doctors by saying, Something is wrong with my son Mingyu . The doctors at the emergency room enjoyed perfect peace . A young doctor asked in a comfortable voice, What do you think is wrong with him? He took a strange medicine, and fell down, complaining about dizziness . Strange medicine? What is it? I dont know . Its like yellow water . Someone with no medical license gave it to me, saying its good for Mingyu . I had my son take it, believing his words that the medicine posed no harm at all… It looked like Byungwon was ready to cry at any moment, but he controlled it, with his teeth set . The duty doctor examined Mingyu with a stethoscope carefully, checking his pulse and blood pressure, and tilted his head, saying I dont see anything wrong with him . Hes just sleeping at the moment . Any poisoned food or toxic substance? Not at all . Maybe he will slowly show reaction to the medicine he has taken, so lets see how he reacts . By the way, what is the medicine? I can prepare properly if I know its substance when he shows some reaction… Let me call my friend about it then . Byungwon opened his mobile phone to call Hyunwoo, where he found Hyunwoos text message .
