For special deals, like the Dreamy Rendezvous pack, that you need to complete a set of missions to get all the rewards, like clearing chapter 4 of the story. Is a problem that it will go away even if you pay for it, locking you out of some of them.
This discourage potential buyers that joined late, because they may not have the time to complete the missions. Losing a potential investor in the game.
I would recommend that, if a person buy a pack with missions, it is at least extended for 2 weeks, to help them to unlock the rewards, if not just make it permanent for them until all rewards are cleared.
Would that be possible?
