XD See, it is a cute series~ (But Seryou is... That one line. Something about being tied to or up.) They're all adorable and I really can't believe they spent half a week being oblivious to the other's feelings.
And I can try to help with Seven Days~ (The deck; I still need to finish Mercurial.)

Oh, have you tried Gravitation? (I haven't, but I'm collecting a main character's deck.)
