THIS HAS SPOILERRZ
So basically the dude who w the hat is actually her husband and she's being stalked by the dude who tells her that she's being stalked (let's call him ass) and so ass actually thinks that she's Yeona which she's not and Yeona is actually her daughter that he had been stalking before this and she had passed away and now the mom is on a trip to kill herself because she feels so bad about her death and her husband is stalking her to makes sure that she doenst die and ass is being a fucking creep.
