Blossomed affection will actually be added first and be available for every character. The limitation there is the number of hearts(for unlocking it) and gifts available per month. DMM was only adding bloom evolutions for four characters per fortnight until recently.
With all the talk of saving dupes, there probably should have been recommendations to save Life Crystals and Sun Medals too. Those are what you need for buying the hearts and gifts. Buying gifts for Bond Crystals(the dupe character currency) was added a little later.
If you thought dragons were a pain in the ass to farm for normal evolutions, oh boy are you gonna enjoy gathering blooming materials!
No less than 3 different kinds of relatively uncommon mats for each bloom too!
I'm not so worry about how hard to find bloom material.
Namely will make some special deal that come along with bloom stuff for sure.
Or maybe he will put it in shop for trading with NG.
The real pain part is player will starving of gold.
Bloom use more money than evol, and with max lv raise to 80 it's mean more money spend for upgrade.
Nutaku don't have free increase gold drop campaign like DMM.
So only you can farm gold in short time is pay and run Morimori as you please.
