Be my Princess/Ouji-sama no Propose - event stories and JP app

Hi, hello! I've been a Be my Princess 1 & 2 fan for probably about 10 years now and it's always been one of my comfort games! One thing I've always disliked about it though, was the lack of fleshed out butler routes. As much as I loved the princes, the butlers seemed so much more interesting in comparison!

Unfortunately, I was pretty young when the party version was originally released, so I missed out a lot during its prime and wasn't able to get the event stories that featured the butlers :')

I remember some of the events that were released before the app was shut down, like probably around 2014-2015. (Ex. The Stewards Beach vacation and The private lives of the butlers?)

Am I right to assume that none of those special stories, except for the gacha stories, are accessible or purchasable anymore, not even in Love Tiara? And do routes exist for the BMP 2 butlers in Be my Princess Eternal Kiss?

Is there anyone else who's as much of a fan as I am? :')
