The Last Man

From comic natalie:

"The Last Person" is a human drama depicting the pride of a funeral director. Kotaro Soyogi, who works as a salesperson for a medical device manufacturer, meets a quirky funeral director, Sosuke Shie, when he visits a customer's funeral. Kotaro, who was worried because he couldn't find a reward in his current job, asked Sosuke, "What's the best thing about a job that touches a corpse on a daily basis?" Was "You're more like a dead face." At that time, Kotaro received a phone call from the hospital where his mother was hospitalized.
