IDENTITY OF SHOW
Thanks to Izumisano of MashaPlus Info Forums for the information.
This is a skit called Mirai Nikki (Future Diary 未来日記) in a TV variety show called the Unnan no Hontoko! - read about it here. Sakurazaka is the theme song for the Mirai Nikki segment.
The YT clip shows the last episode of the Mirai Nikki Part V "Sketch Book". A surprise happens at 3:05 that no-one expected. Much sought after clip in the fan community!
A dating variety show?? The surprise is at 3:20 actually. And I was right about the title!
