Side story: Chemistry

Chao woke up after a long night of sleep. He was hushed to the bed by Yitian really early yesterday, but Yitian went with him, so Chao didn't mind. It was just that he needed his 'beauty sleep' as Yitian said. 

Today they were going to the photoshoot. The set was in the Kowloon town so they had a long wait to get there and even though the photo shoot was scheduled in the afternoon hours. They still had to get ready and be there an hour earlier, take a shower at home, and wear nice clothes.

Chao was alone in the room, so it meant that Yitian was already up and getting ready. Chao smirked and imagined something naughty in his mind. But then he felt startled by it. He frowned. 

Why was he thinking about Yitian like that? He liked him, but did he really wanted to do with him the things he imagined? Was that the way he liked him?
