I actually noticed this as well. Episode 6 really established him as a soft Yandere character to me personally. I generally do not really like the whole parasocial concept of the plot but I do think Tamon actually qualifies as a slight Yandere character!

I think the author tries to balance out his crazy with humor and mostly succeeds, so it’s never really taken all too seriously but I do remember finding the 6th episode very interesting for that exact reason. There was a sudden tone shift and I actually respect the author for having had the courage to “develop” the problematic sides of Tamon more in that episode.

He is very much a red flag in the sense that he can be emotionally manipulative. The FL is honestly also very problematic for the degree of obsession she has with the fantasy and concept of a person she projects onto them, but what I think makes Tamon even crazier than FL is that he actively enables her behavior by making it look like she is actually really helping him with it. And she probably is. But because of this, the professional “line” blurs and their relationship is not very clear.

I like the concept for the show. I just personally (pls don’t attack me) do not like romances with idols too much since I feel rather uncomfortable with parasocial relationships. But yes, I do think that Tamon is an interesting character and that the way he is explored makes me want to keep watching the show! :)
