Chapter 1: no, don't change the pov ! i actually enjoy
the changing of point of views; from baekhyun
himself to 3rd third person, tbh i find it very
unique ! also it's pretty easy to follow through,
cause baekhyun is mainly narrating throughout
the story. as long you read at your own pace and
understand the plot/concept then you should be fine
i see no difficulties (:

so far, so swell ! keep it upppp ;)
&& nice poster poster .

Chapter 1: Only one chapter so far, but I really liked it, and I look forward to reading the next chapters :)

I especially liked the style of writing, and it's simplicity. +Short paragraphs are nice to this kind of fic.

One thing you might wanna do next chapters, try to choose one point of view, or note when the point of view is changing. It wasn't very difficult to understand whose view point it is (changing from Baekhyun to 3rd person), but because you have short paragraphs it can still be confusing to some.
The easiest would probably be to have the whole fic in 3rd person, and just add "Baekhyun thought" or something of that sort.
