ATEEZ San’s Recent Remarks About His Sister Sparks Massive Backash

What are your thoughts?

Recently, photos were posted online revealing the ATEEZ members attending San’s sister’s wedding.

Fans were touched to see that all the members attended the wedding, despite it being very far and San not wanting to bother them.

However, his recent message to fans about the wedding received much criticism online.

My older sister says she’s happy, and that is enough. I was worried because she is so sweet and pure, so I am glad that my brother-in-law is such a good person. Now that she’s getting married, I told her I wouldn’t be able to call her by her name anymore and would start using the term ‘nuna’, but she said it was uncomfortable and asked me to keep calling her Haneul. But I told her that I had to be respectful to the brother-in-law, too.

Please take good care of my sister. I wanted to share this moment with you all. My heart felt strange LOL. I didn’t cry, but I cried in my heart.

Netizens were shocked that his reason for switching back to honorifics was not for his sister but for his brother-in-law.

최산 진짜 한남 찌릉내 오지긴하다
누나한테 평생 누나라고 안부르고 이름 막 불러대다 결혼하니까 누나라고 부르겠다는 이유가 누나한테 예의를 갖춰야해서가 아니라 매형한테 예의를 갖춰야해서^^
걍 여자를 뭘로 아는지 알겠음
한국남자 그자체 https://t.co/LUVRTLQmzJ pic.twitter.com/iyyjvIiBa0

Choi San, you really reek of a Korean man. You never called your sister ’nuna’, and now that she’s getting married, you decided to call her ‘nuna’ to pay respect to the brother-in-law. You can just tell how he sees women.

누나 이름만 부르는데 부모가 내버려둬? 우와 https://t.co/ux2i8m8GgV

His parents just left him alone, even though he was calling his older sister by her name? Wow.

He needs to change his name from San (mountain) to the ground. Does he really not understand what’s wrong here?

매형한테"도"?ㅋㅋㅋㅋ 아 개좆같네 뭐하냐? 병신이 매형은 사람이고 누나는 사람도 아니냐? https://t.co/KhXHCDrVEL

For your ‘brother-in-law’? This is f*cked up. So your brother-in-law is a person, but your sister isn’t?
