The Delusion regarding two people

Groggily afflicted with writer's block that has her on thin ice in her professional life, Ruriko is in no mood to celebrate Mikako's happy-go-lucky homeostasis of having embraced Tsutomu as her paramour since the turbulence has compromised her work. Further inflaming matters, the stress has accumulated to more than what Ruriko can handle on her own as she prosecutes all kinds of dystopian scenarios of Mikako and Tsutomu's future married life. Tsutomu has it explained to him that his new romance with Mikako is community discourse at school and it is suggested that Yuusuke has a strong mutual affinity for Mariko while Mikako's thoughts are split between the practice lab and Tsutomu. Frenzied by work-related stress and the dystopian scenarios of the future, Ruriko ultimately panics with such fervor that Mikako summons Tsutomu over for help.
