For me this is not worth anything at this time because I have only 2 Jewel girls with 2nd affection and they are already at 98% each lol.

Looking at other Jewel girls who I could raise 2nd affection also shows me only girls I don't use for anything but whale ship so it's not important enough to pay RL cash.

If it was cake tho.... instant buy! I have so many hungry girls... Need to open an all you can eat cake buffet.
