[All] Looks like there's a Rise Gold Stamp Challenge event.

 

The Rise Card Stamp Challenge event is a limited-time promotion held by Mega MGC Coffee and Rise. Each time you order a self-participating mission combo menu, you'll receive a stamp. Discounts are offered for the first and third rounds, and capsule photocard vouchers will be given out on a first-come, first-served basis for completing the fifth challenge. You can easily participate in this event by clicking the "Participate" button on the challenge page within the app, ordering, and picking up a mission class menu.

 

I think you get a stamp every time you assign mission 2, and you get a discount when you participate in missions 1 and 3.

You're good at marketing. The company must be doing well too. Haha.

The process for participating is simple, and fans can receive discount coupons and regular photo cards to enjoy Rise's summer season drinks and accessory combos, so it's bound to receive a positive response from fans.
