Yes i see what you mean! Hanbin himself said that he was pretty "dry" when messaging people (who are close to him). He would send super short answers or abbreviated words. I think he also trended once because fans asked him to act like he would naturely and he was a bit "rough" for lack of better words lmao. We know he's naturely super kind and sweet, but he seems to strictly separate his idol image from his real self. Hao told him that he didn't have to act nice towards him, that he could be real. I find this amazing because it means that he completely trust hao and has opened up to him
