Chapter 4 summarized:
MC wakes up in the hospital, after 3 months in the dream world. MC promotes Han (his friend/employee) to CEO, to avoid dealing with all the work stress and as thanks for his help. His wife is now acting as the new CEO's secretary. She also mentions a new treatment for his condition. Cue hospital treatment scenes... later some secretary phone call scenes...
MC organizes a party. He meets a white haired woman (old acquaintance?), whose husband is also stuck in the dream world. MC offers to help her, and is about to learn new info about Adrian (demon) and the dream world, when his wife interrupts them. MC, his wife, and Han leave the party to check the new results from the hospital...
On the way to the car, some goon from MC's old business hits on his wife, and Han protects her. MC then meets and scares the goon, before going back to the car...
The three of them go home. Wife tells MC to sleep in the next bed and to sniff her dirty stockings, she wore to the party, and convinces MC that Han is sleeping, and not currently groping her. END.
