this is insanely romantic. i'm sold. like, i'm already a sucker for class S-inspired stories (marimite, anyone?)
I always thought Marimite is a weird one. Yes, it has all the surface elements of a Class S story (sisterly bonds, rosaries and the like), but almost none of the elements that make Class S so distinctive. Most classic Class S stories have a heart of love, longing and outright lust, and Marimite has almost none of that. It's mostly the antics of high school girls who like role-playing Class S tropes, but there's no there there, if you know what I mean.
The few times Marimite seems to be going into a more romantic direction it gets treated as if it's something to be avoided, such as Sei's backstory. It's also telling that by the end the only official couples are heterosexual ones.
Strawberry Panic, for all its silliness, seems to get al least the romantic and lustful part of Class S right.
