I am just going to list some things that I liked/dislike and can be improve about the special episode:

1. Phayu and Pai's friendship
2. Rain and Sky's friendship
3. NC scene (Daddy scene)
4. Expanded from the series
5. Rain's Kink
6. Vacation theme - it was different than most BL special episode as it felt liked written like a normal series would be and not the characters just popping up to a theme park or something.

Dislikes:
1. Lack of content - their should have been more scene's from both couples.
2. Short - the episode was short which sucked especially since we are covering two couples.
3. Production - it wasn't bad as the series but it was just like the first half of phayu and Rain's arc where the sound was okay but it could have been better.

In conclusion, to address the elephant in the room the pricing was not worth it granted the episode could have been longer, however I do recommend the episode itself as it was good. It was a good send off for the fans and the cast members as well.
