Mr. Smiley

Mr. Smiley is a man who is assigned to lower suicide rates in prisons by Doctor Money, as the protagonist's personal happy-buddy (tm). He seems upbeat and happy and is very friendly to the protagonist. He contacts with the protagonist via letters, which their covers are addressed as "Doctor Money's Happy Buddy Initiative", using blue envelopes and three kinds of creatively aligned fonts, with a smiley on the top-right corner.

During Day 2, the protagonist receives a letter addressed to Mr. Smiley, revealing that his daughters were kidnapped and used as blackmail, and he is required to fulfill a "happiness quota". He assures the protagonist must stay happy, and hints that if the protagonist commits suicide, he will be responsible and be killed, and mentions more and more inmates committed suicide during the several days in game. By attempting to please the protagonist, Mr. Smiley sends them these items: Doctor Money's Portable Entertainment Product (abbr. PEP), five confetti poppers, five games (installed inside PEP), and a poster.

On Day 4, by buying the fourth game, he sold his food, belongings and one of his lungs. It is later revealed Mr. Smiley knows the protagonist is not infected with the virus, and therefore has a solid reason to forsake his life for the protagonist.

On Day 5, Mr. Smiley tells the protagonist his true motive, and reveals that his daughters had died 2 days earlier because of the infection. He has requested to sell his remaining organs, so he can buy the protagonist one final game, and encourages the player not to give up as he does.

As he states, selling all his remaining organs will cause himself to die due to lack of sustaining organs, therefore he supposedly dies in day 5 or soon afterwards.

Mr. Smiley says that he was never the player's friend, but this may be false as he kills himself in a way so he can buy the player a final game rather than simply killing himself.
