Shiho swooning over Aki is great. Talk about a "gap." I imagine Shiho nearly fainted when Aki said, "That's my girl." Plus Aki is also clearly, very much enjoying this dating thing and predictably wears the pants in this relationship. Watching Aki flirt Shiho into submission will always be funny to me.
They already seem so comfortable in this new stage and I can't wait for more interactions, leading to the inevitable kiss. Her acknowledgment of Hima and Aki's bringing her along and saving her from herself was also appreciated. She's got to take them both out sometime, maybe during a double date? Edit: the flowers are for Kyou's grave. Thanks for the correction!
