In Han Fei's home, the only thing about that game labeled as "Healing-type" that had anything to do with healing was the game's label on the helmet, which seemed to have been added later by the Shop Manager.
Yet, it was this very game that initiated a change in Han Fei, forcing him to open his reclusive heart through a method where non-socialization meant death.
It also taught Han Fei how to communicate with roommates living under the same roof by having a serial killer visit.
Gradually, Han Fei began to actively get along with his neighbors.
Eventually, he, a man with severe social phobia, was even elected as the Building Chief.
Although the means by which the game healed a person were somewhat crude, the result showed that Han Fei had indeed changed; he had become a better version of himself, standing on the stage of his dreams proving everything.
Ultimately, the "Perfect Life" game indeed had a healing effect.
