They changed a bunch of things with this mini-update.
First of all: so many things are behind an actual paywall, instead of behind a game-currency (like chocolate). Many fans are mad.
Second big change: When you go to the With Him page and click on the magnifying glass on the top left of the page, you get the list of all the affinity levels and their related rewards. Well, now, FINALLY, you can tap on each affinity number and see the message you get when you unlock it. Before this update, fans had to ask other fans if they had saved those screenshots, and we had to rely on notion pages where fans put those messages up.

Now, onward to the promise.
You've already seen a few Promise events (remember when I told you about Raf's promise card Banquet Ablaze that's lore relevant but stuck behind a paywall?), and they usually work this way:
You have 2 LIs together per promise event, with 3 tiers. 1 is the free tier, it will get you upgrading resources but no card. Tier 2 will give you more resources and you can choose the card of 1 LI, which you will get 4 times during the event so that you can rank it to the max. Tier 3 adds just a couple of bonus items, but most importantly will give you the second LI's card, fully ranked.

What you're seeing now is the rerun of a past promise. I've seen another couple of reruns in the past, most notably the oracle of scam (stars) when you were already playing the game. This is a new version they're testing out I guess.
I don't know how it's going with your currency, but let's say the price is 9.99 dollars to buy 1 of the 3 LIs' cards. Once you have it you'll get the corresponding free item (Raf's has fluffy bunny, Xavier has Infinite Future glasses - they're the ones we use to glitch the hair, if you were to get it you'd need to use another item to trigger the glitch, and for Zayne Floral Melodies). Say you also want the reward box in the middle which gives you 3 titles and 10 empyrean tickets: you have to pay 6.99 dollars.
Say you want to rank the card you just got: you need to pay 200 purple diamonds for each rank (600 purple diamonds in total).

Say you're done with 1 LI and want the promise card of another: do it all over again. Pay 10 dollars for the card, then 600 purple diamonds to rank it. Additional 7 dollars if you want the 3 titles and 10 emp tickets.

Is it costly? Stupidly so.
Is it worthy? I can only say: depends on if you like the cards and if they're in a stella that you care about. For me, for example, the great doubt is that it's a green 4 star so I wouldn't need it (I already have a full team of 6 green stella for Raf thanks to the beach banner), but I do like the story in it, and my completionist ass is trying to push me toward getting all the Raf cards I've missed.
So check out the card stories on youtube and see if you vibe with them to the point of spending 20 dollars to obtain 1 card fully ranked.


You also have the current Summery Promise event with 2 tiers. The free one gives you upgrading resources, whereas the paid tier at 6 dollars will give you one of MC's beach outfits and then more upgrading resources.
If you were to buy the outfit from the shop, it would cost you 6 dollars in purple diamonds, so it would make sense to pay them for the promise so you also get the added resources. But in case you gathered purple diamonds through the aurum pass, you would have already paid for them, and paying for the promise would be an additional cost.
