The thing occupying my mind is that the guy acted unexpectedly. Just what is he trying to do and what is he thinking? You'd think he was pretty straight forward with his intentions obvious and the next thing you know, he just acted differently. So he's friendly with Yeon. Ok. Then, he was curious regarding Taeho because he's pretty close with Yeon. Maybe he's as upset about it as Taeho is, despite saying he doesn't care. Ok. That's the impression I got... now then... he discovers that Yeon and Taeho just met not long ago and yet they already act like this. Based on what I think he should know by now: Yeon is rather close to Taeho (or at least acts like it) despite just meeting not too long ago. It seems Taeho is unaffected by Yeon's "magic". Ok.(if he's aware of that magic).
So...
Why did he want to recruit Taeho? Based on what?
Now I'm really looking forward to what happens next.
But... if his direct "intentions" so far are an indicator of anything, and he's acting indirectly... that he pointed out that Yeon and Taeho are close despite being close to Yeon... and then finding out certain things and deciding to recruit Taeho...
It's either he's curious about Taeho and thinks it'll be to his benefit if such a person who's able to become rather friendly with Yeon can help him somewhere...or that he's "eliminating" prospective "rivals" by doing this - distancing a formindable predator from a prey by taking said predator under his wing so ehe could have prey for himself? Even if that predator is passive; the prey is rather attached to him.
I dunno, maybe I'm just thinking too much.
It's because he's really weird!!!
either he is the type whom can act like a friend when under the curse or his aim is really the manager. Our main character should say no to the question asked upon him. After all he is a perfect fit for being yeon's manager doesn't mean he would be good for another.
