It’s mentioned I think earlier about how the company wanted to work with jay
But it was a mystery who they were I think
Since the first time Dokyung show up, he always brought 'Jay' name. But the person is a mystery, nobody ever know who Jay is, they just know the name and the reputation that Jay is some extraordinary architect. Then Anna spoil it that Jay is Minjoon, i think when she was talking with Minjoon when the news about Minjoon and Hansol dating up to the surface.
Wait when did they start talking abt "jay" like I don't remember that at all
