Ah so the Vintage member was just Haqua faking it the entire time eh? And here I thought there was actually a chance they would be in danger.
Still it's good that Keima finally got Mars winged. Now he'll have to explain the situation, but I'm sure just like the other 3 goddesses she's not going to approve of the so-called "four-timing".
As for my guess who's next, probably Shiori/Minerva, since Wakaki may be hinting at that by showing her recently.
