Monochrome Rumor

Rumors circulated that he only cared about money, had blighted affairs with his adulterous sponsors, and abandoned his fellow group members he had known for two-years after renegotiating a contract with a major entertainment agency.
He had taken possession of the body of a hopeless idol whose common moniker was “Beautiful Scum”.
He thought he got blatantly ripped-off by signing that contract.
Everything aforementioned had been far from his actual self. He was a sob-story right out of a melodrama; not even close to being ‘scum’.
This was the tale of how he, enraged by the body of the previous possessor’s shitty life, personally took revenge for him.
So far, everything had gone accordingly. However, in the process, he gradually tamed the people around him.
He posed/masqueraded/feigned his pessimism as optimism.
Sometimes he appeared stoic, and other times cordial,
Whilst simultaneously acting innocent.
He was the sole person unaware of the harem that, little by little, began to encompass him.
