does anyone have an idea about season 4 of this drama???? is there gonna be one??? as it comes after two years so.... is there any news about season 4??? cuz the third came in 2015....... I really want season 4!!!!!!!

I check on aramajapan and wikipedia japan and nothing about a season 4. Sometimes, seasons are revealed less than six months before the airing... cross your fingers my friend ^^ Code Blue has a third season after 7 years...
Im not  sure about this but I found this https://news.nifty.com/article/entame/showbizd/121...
it's in Japanese but using google translate + the little I have learned of Japanese, I think there will be a season 4 but it was delayed due to health problems of Nogiwa Yoko... Something like that ^^
