Not sure for J, but I know TJA and Zev from NUS. I also dk how their names popped out here.

TJA is NUS, notorious insurance agent u all shd be aware. Burden his project team members to tank everything while he busy outside hard-selling insurance. Go see his insta.. very cringe, very bad reputation in NS too. He was part of the NUS entrepreneur group but his previous business (watches) - just basically buying cheap and selling high.. stupid idea.

Zehvi is just some ****boy la. Go around sleeping with girls. He good looking and rich (cos daddy rich, heard his rich dad gave him BMW for enrolling into NUS?)

JSng i dk much about him. I used to follow his insta, always flex his benz or money one. dk him personally, just know he is a rich dad's son
