Marigold in 4 minutes is an incomprehensible title the explanation of you get only in episode 9.

Mii is an ambulance worker and Sara is his step sister and a painter. They are in love. But Mii has a strange ability: when he touches someone's hand he can see their last moment. This ability manifested itself when, as a child, he touched Sara's hand and saw she was going to day on her 28th birthday. He decided to save her from that fate. So this is the main plot. Every episode also features an EMS "case of the week" which are a learning experience for Mii and his family.

The drama works very hard to impress upon the viewer the importance of appreciating life to the fullest, living each day as if it were the last and have no regrets, doing what is important and what will make you happy because this is the only life you'd get.

Rather corny and very much obvious. Still, it does not hurt to hear it again and again because we tend to forget what is important and we lose ourselves in tiny details and tend to make a mountain out of a moathill!
