I wouldn't say she's worse than Sakura yet. Even if the reason she's doing this is absolutely retarded.
Unlike Sakura, she hasn't crossed the line. Not yet. But her initiating and pouncing on the actor and, if correct, this being done out of spite is definitely a MASSIVE red flag.
With any luck, this could be the final bait of the manga. Or it could go full with the scene but no penetration. I'm at least expecting some boob play so we can only wait and see. There might even be some tongue action from her end. The actor himself seems really puzzled and surprised and may or may not go through with it.
