So I scroll through my tumblr and i find this post about Baekhyun hurting Sehun during Overdose practice and Sehun getting mad at him.

The original post is in Korean. I picked out bits and pieces of it. I can't understand 100% b/c of the slang. Sorry, idk Korean slang :\ (like text language)
But it starts out with Taeyeon's previous dating experiences with other SM singers (I'm not a SONE so idk if they are true or not). Then the author moves on to explaining what happend on stage (with gifs and picture) and ends with her commentary. And let me just tell you straight out that her opinion isn't very nice. In fact, it isn't nice at all. It has a lot of cursing, with most of it directed to Baekhyun and Taeyeon. 

The last three sentences mock the two by saying "Have a nice relationship~" (obviously mocking tone considering her words before) "탱쿵붸링망칭" (which means 'Thank you very much' but contains couple names that Taeyeon and Baekhyun made through play-on words. I think one or both of them wrote this on a IG post) and "Cucumber♡Baekhyun Cumcumber loves Baekhyun" (if you don't know, Baekhyun can't eat cucumbers-pretty much hates them I guess-so that's saying no one likes him except for cucumbers)

I'm not sure why those two are acting that way, but it breaks my heart. Exo is already in a bonfire, and this is just like feeding gasoline to it. I decided not to translate some of the commentary, because idk if you guys want to hear it or not. So if you want to know, comment and i'll reply. If you don't want to know, just ignore the comments.

here are the gifs and picture if you can't see it on the original post.
