In a surprising turn of events, a Malaysian woman took to the Facebook page "XUAN Play" to anonymously share her unsettling experience during the Lunar New Year. She brought her boyfriend home to meet her family, and everything seemed fine until she discovered her younger sister's inappropriate interest in him.

Despite the abundance of eligible men in the world, the younger sister fixated on her older sister's boyfriend, even going so far as to make physical advances! Netizens couldn't help but exclaim, "What A Conniving B*tch!"

The incident unfolded when the original poster (OP) brought her boyfriend home for the New Year, and her family, including her parents, had a favourable impression of him. However, things took a bizarre turn when the younger sister began showing a keen interest in the boyfriend. She even went as far as wearing revealing attire to intentionally attract his attention when he visited.

To make matters worse, the boyfriend informed the OP that the younger sister had crossed boundaries by touching him inappropriately. Adding to the drama, the OP discovered that her sister's phone wallpaper featured a picture of her boyfriend! 

In the original post, the OP expressed her concerns: "Last week, I brought my boyfriend home to meet my family for the new year. My parents had a good impression of him, and I was happy. The only problem was my younger sister. I felt she was acting strange. Since meeting my boyfriend, she has been asking a lot of questions about him. Recently, when my boyfriend came to my house, she even wore a revealing outfit to flirt with him. At first, I thought she was just chatting, but my boyfriend told me she touched him inappropriately. I told my parents, but they said I was overthinking. When I confronted my sister, I found out her phone wallpaper was a picture of my boyfriend. She told me it was okay, he's handsome, and she should be allowed to enjoy the view. How do I talk sense into her?"

Netizens were bewildered by the sister's behaviour, with some labelling her as "b*tch." Some even suggested that the OP should consider letting her sister have the boyfriend.

With the younger sister eyeing her older sister's boyfriend so keenly, will this sisterly relationship survive?
