Djsjdhis i was discussing this with my friends not long ago. Tbh i can see it being real because like you said, haobin are crazy like that 😭. What's funny is that, according to the same rumor, hanbin was saying things like "i wish hao was my brother", "i wish hao was my teacher" and then full on pulled the "i wish you were my bf " later sjejzkzk. He was testing the waters while hao was like "don't say that". Kinda reminds me of the tietie scene, hao was trying hard to act nonchalant while hanbin was exposing him. So yeahh whether it's real or not, it's definitely something they would say 👀
