After months and months... and months of being unable to play properly for one reason or another, I've finally gotten back to taking Battle Rondo somewhat seriously. After a few runs of tending to the girls, I notice that none of them seem to like being patted on the head anymore, and have fairly bland wake-up greetings -- this includes the Maochao that I've kept around at max level with a ton of wins(albeit at EX) and who I've come to depend on being totally in love with me.

So what happened to everyone? Does affection decrease after not logging into BR for so long? Is it just that I wasn't waking up and using everyone every time I logged in?

fat lot of good that CSC Restore did for Mei, with no affection to keep orz

yes our darling little ones get angweeeeeee when we dont see them often

like any significant other , they'd get the shxts when not being attended too or having any attention
its like the other Konami game "Love Plus" , don't come on your Nintendo DS often and get the same treatment

The longest I've been inactive was probably a month, but it didn't seem to do anything.

I haven't seen Fubuki in about a month and she got a bit upset at me. I took her into 5 missions and she lightened up again . So ya, take care of your gals whenever you can. If you get bored you can use the "affection" as an excuse to get back in.
