How will rerun’s work?

So the only ever other gacha game I’ve ever played is Ikemen Sengoku and they had reruns of some events. While some things such as gowns, accessories, pictures and some (not all) parts of stories were rerun, they’d also add new characters to that rerun. This was an absolute win for new players because yay new event but for those who are replaying it they give new content so you don’t have the same repeat stuff as last time. The exception was usually birthday events and anniversary events, those were always different (aka new gowns, storylines, room decorations, etc) So that’s got me curious for reruns in L&DS, specifically the ot4 banners. It’ll be awesome for those of us who missed specific banners/ weren’t able to get all the cards/ weren’t able to rank up all the cards, but what about those players who are fully ranked? Do you guys think that the devs will add some sort of new content to those rerun banners? For example the gem hunt; instead of stacking up gems they have a game like the kitty cat event where you have to ‘mine’ for the gems, like you’re in a cave and u have to click a certain amount of gems within a time limit. And instead of the battles/ stories for the guys, it can be like a photoshoot theme. For birthdays it would be nice if they of course had a new card but also a rerun of last the birthday cards (the only downside would be once this game is over 5+ years old collecting a ton of cards on a bday might make new players frazzled). I’m really excited to see what the devs will cook up and I’ll crawl to infold and beg on my hands and knees for reruns of past banners I need them so bad.
