Extra Episode Warning :)

Yoyo English channel updated that there are 3 premieres on youtube for tomorrow for this drama, tho I am a little confused that there's an extra episode which is Ep 25 ~ Special Scene so it's making me curious as to what's gonna happen in Episode 25.
In my opinion, I think that this drama is the best one I've watched so far since it's a romance drama. I love romantic stories. The storyline to this got me very interested and is watchable on repeat. I don't know what to say really since this is my 1st ever review of this drama so be polite if commenting.
