"Ah... Well ... Uhm... Yeah... Sorry, I guess..." Ren uttered as he let go of Ryuu's hand. He blushed towards the floor and his heart pounded a bit. He didn't know what had come over him. 
Ren turned around, obviously flustered and walked towards his desk where he put down his bag. he grabbed two forks and a knife out of his drawers. It wasn't the first time Ryuu had brought something food-like to his work, though it had gone more smooth before (without all the nurses), so he was prepared for stuff like this. He went to sit onto one of the beds that he had in the room in case he had a night shift, and tapped on the space beside him, inviting his friend to sit next to him.
The atmosphere was still tight and awkward, but that's also why Ren didn't know what to talk about, especially because his face was still reddish and his heart rate elevated. He normally wasn't so easily flustered, but today it was different and it annoyed him a bit. He glanced up at the other male to see if he got his invitation, yet it seemed to aggravate the condition of his face and heart.
