Eventhpugh this drama is good, the airing calender and available episodes don't match. On the calender it says that this week it will finish or be on the 23 eps or something but in realty there are only 12 (except 9 and 10) eps available. I also checked it innthe original language and couldn't find no more than 12 eps. It is very dissapointing.
I found this serie on viki but only 3 eps were free so I watched it online. On the internet they only didn't put eps 9 and 10 other than that everything is fine. I don't really understand how it is possible but... If you wanna watch childhood friendship becoming love you should definitely watch it. It's kinda sweet.
