This being Tamon's face after he threatened his fan with suicide.
Don't get me wrong, I love him, but he's so manipulative. It's part of what makes him such an engaging character. And it's balanced, because Utage is 100% aware. She goes through it eyes open, like "Tamon is a massively successful idol who's entire job is to manipulate people into loving him. Him turning his entire power on one person is almost impossible to resist". And it was. He kept escalating until he reached his goal, not even stopping at SUICIDE. The man literally said he was willing to sell his brain (which obviously not, he can't be friends with her if he's dead), entirely for the purpose of manipulating her.
And it's just because he's desperate. He has no one else, and he WANTS no one else. He unapologetically uses everything in his arsenal to manipulate her without remorse.
And I just think that's pretty neat. People talk about Tamon's two-faced nature (its literally the name of the anime), but they don't talk about how much of that is intentional. It's calculated. Tamon is socially ostracised and anxious, sure, but that experience has also made him an expert at manipulation.
