Teaching emotions to a machine is harder than it looks.
About
In modern Japan, technology has advanced to the point where humanoid robots are mass-produced. The current Mark 52 models are human-like, while the Mark 28 is a twelve-year-old relic. Tetra Robots are sold everywhere.
For reference: "Tetra Robot Mark 52 8TB → 350,000 yen" "Tetra Robot Mark 28 1TB → 400,000 yen (at original price)"
