I think there will be a season 2 with the new guy in it as well maybe. I would be disappointed if he was bought in at last minute just so Ken could tell us about how he met them.
I love the bride part of the episode. I would have done exactly the same as Ken in that one. So cute how that scene went.

I would have also loved a good ending where Ken trips and kisses new guy by accident. Ending with them on the ground and we look up at Mafuyu who already has the camera out all the other girls are stunned and flash of Mafuyu camera goes off and starts the fade to credits. Brings in a new season and ends the previous one on a good note. But that is all assume there is a second season.

Probably not though because I don't think they have much material to go on any longer apart from the others confessing to him.
