This chapter is a continuous chapter from the previous chapter. So as you know, people are saying Sehun and Baekhyun are on bad terms because of Taeyeon. Well, the truth is out!

This is the performance when Baekhyun slapped Sehun and when Sehun pushed his hand away. Skip to 1:25.

As you can see, Sehun was on a total poker-face mood before Baekhyun slapped him but smiled after Baekhyun slapped him. So it is obviously an accident.

Sehun also did not push Baekhyun's hand away. If he did, his hand should be under Baekhyun's hand and not over his hand.

And about Baekhyun's fingers digging into Sehun's skin, most likely that was also an accident. 

This shows us that gifs and reality are completly different. In the gif it looks like they were really on bad terms but in reality they are on good terms. So yeah, please do not believe in any rumours.
