Jiang Cheng has been friends with Nie Huaisang for years. Since they first met in high school. Jiang Cheng knew Nie Huaisang to be everything people didn't expect from him. He were always perceived as young, sweet and innocent. In reality Nie Huaisang were the same age as Jiang Cheng. He were also not very innocent, having much too many erotic books and films in his possession. And his 'sweet' look was also rather deceptive as Nie Huaisang could be rather bitchy at times. Very regularly actually.
Jiang Cheng was rather intregued when Nie Huaisang started to show up to their friend-groups weekly hang outs wearing much more conservative clothing. Nie Huaisang always dressed rather provocatively. When asked the man shrugged it off, saying something about how it were getting colder outside. Which was true as it were now moving into autumn but Nie Huaisang never dressed less openly in the last few years prior.
The next incident happened a few weeks later when Nie Huaisang seemed to be unable to sit still. He were constantly shifting and sitting on the tilt of his thighs rather than normally. Choosing to stand whenever he could. It was very unlike Nie Huaisang who was always the first to sit. Once again when asked he blew it off.
This week Nie Huaisang decided to drop by for coffee as he'd miss the weekly hangout, which was on a Saturday, because he had a job scheduled in. It were just him and Jiang Cheng which wasn't odd, they did it a decent amount. The two were chatting away as normal.
