Not entirely sure if this the subreddit for this because its not really a theory. Just an observation. My justification is as follows:

1. Ian: has been in a casual relationship with Nikki for 2 years but wouldn't reveal it to bear to "not hurt him" while fully being aware of his feelings. Gives him bad advice purposely to sabotage his chances (freaky nikki coz he knows she doesn't like it, "all you have is time" when she's going to leave). When nikki is possessed he tells bear about the dad not having cancer not with the intention to help him but with the intention to sabotage their "relationship". He says Bear is taking advantage of her not with concern for nikki, but because he wants nikki to be with him not Bear

2. Sarah: We don't see much of her but still reasons are there. She reveals Ian's and Nikki's secret relationship to prevent Bear from getting hurt as she says but not to help Nikki? Nikki is her friend too but instead of helping her from getting taken advantage of, she uses this chance to get Bear. And she doesn't care about Bear either, she kept the secret from him for 2 year but cares about him now? No, she just got interested in him that's why she uses this opportunity to get him to be with her. If she cared, she would have said something long ago.

3. Bear: Yes, its obvious he's a bad person but even before the OWW (One Wish Willow) was used he was a creep. When the cat dies, he just throws it in the trash bag. When he's crying later, its not for the cat; he doesn't care about the cat. He says "Why can't she just...", he's talking about Nikki. He's crying because he's not with Nikki. Then proceeds to stalk her profile. He was obsessed with Nikki even before the OWW. He does awful things to her after OWW was used, which is obvious to viewer.

When Bear buys the OWW (One Wish Willow) in the beginning of the movie the lady at the shop leaves for a while and he sees the OWW, takes it to the reception. He mentions to her that "What if it does work and ruins their lives" and the lady responds with "and they die or wish they were dead".

I didn't think much of it until later when he calls the number of the box and the voice on the other side says that the wish will go on as long as he lives.

Later in the movie when he goes to the shop again, the man says he doesn't know what the OWW is but the second the other customer leaves he says that its right there and suggests making someone make a counter wish or killing himself

All 3 suggest killing himself as a solution. My theory is the first time when the lady leaves for a while when she's on a call, the next time she shows up she's possessed by the entity. Same with the man at the end, when the other customer leaves he gets possessed and brings up the OWW. In both the instances other people aren't around, its just him.
