I don't know if the sounds toying fitted it but if it's your opinion I guess so? I think he just wants to know how to treat her without scaring her. Seems how she fear him and couldn't help but only force himself to be liked in the end. It's quite tragic, as it's somewhat leave a bad after taste. ( ̄∇ ̄") But I like the segs ┑( ̄Д  ̄)┍
So what he was trying is to be liked and find the best timeline where he have her in his gasps ( ̄∇ ̄") after all I never seen him enjoy toying with her rather he was trying to be gentle at most whenever she was there. And somehow I saw how he petity her situation from running away from him, and that part what he wants to change right?
definitely wouldn't be able to escape unfortunately, which makes it another reason for her willingness to believe his lie even after discovering the truth. she knows its helpless to fight so she'd rather just accept this make-believe because atleast she wouldn't be constantly losing her sanity worrying about it

I think the worst thing abt cosmic horror stories like this is that at the end, no matter if she managed to escape his grasp or not. she's still going to be all by herself, she has nobody except for the god-like entity that treats her like a toy :( And she ended up accepting whatever he told her because she knows this would be the least terrifying option
