This episode is basically everyone having an ending except for Tehno.
Dr khunpol & Champ getting ahead in their relationship, Loe & Fiat moving ahead in theirs whereas Tharn & Type are working to prepare different things related to the wedding and finally getting married.
I would say, adding it as a special episode for people to pay just for 1 episode isn't good, but doing it as the final episode of Season 2 would have been the best.
I watched the series about a month ago and just found out that it has 1 special episode that I missed.
