Spoiler alert!!!
OMG,she is a stalker!!!. Oh my God, it gives me creeps!!. Think of someone watching you constantly.
Who even gets 'i have to kill' jealous on the 2nd day after seeing someone.
She doesn't work but she has lots of money to waste, i literally was shocked when she poured those many bottles of wine.
After that,I thought who would be the killer, then comes your disappointment. It ended like a comedy show. There is no way a 9 year old would have so much brain to do that. Killing alone is a different level and planning it correctly to cover the tracks!!!
