You cannot be fucking serious.
I can be serious and, in this case, I am.
It is always possible that the quest has been changed, but I don't recall seeing anything in any of the patch notes about it being changed in any shape, fashion, or form.
When it first came out it really was a steaming pile of shit of a quest.
The character would only show up from the 1st to the 4th of each month. You had to buy the dragon fruit drinks every day.
There was a limited supply of the drinks and you could only ask him a limited number of questions each day, all of which was to do nothing but drag out the process of gaining access to the 'vaunted dragon TF'.
Also, the actual quests could drag out long enough that you literally did not have the time to complete them all in the 4 day time frame and would have to wait yet another in-game month to complete the final quest.
If you are serious about going through the quest, I really recommend that you use the debug option to roll back the game date to the 30/31 of the month and then spend a day sleeping for the month to roll back over to the first of the month and pick up where you left off on the quests.
