Just throwing this out there, but for those who can't play often enough to avoid big hits from her stats being low...

Assuming you average more than 66 coins per game, gifting roses bought from playing games is more affection per energy than the affection you get from bathing/eating.... and as far as I can tell there isn't anything to keep you from doing it all at once, and thus not have to worry about affection hits.

(or is there a limit to how many roses you can gift at once?)
