It's pretty hard to see getting to 50,000 bouquets, I got both the n-gacha right away and have used pretty much every stamina I can on searching and have only gotten to 1,393 in a day and a half. Unless they become much more common later on, that one's not happening, it seems (I do have a lot of stockpiled peroanamins to use over the weekend, but it still seems hard to envision those getting me much more progress on this).

At location 57 though, so definitely making progress there.
