I love how Karma actually take care of Sheila as her own child. Sure she is still clinging to mother archetype but the fact she take care of another person other than Ryuuji is a nice development for me.
Thanks to Karma, Sheila now comes in two versions of adorable! And she got married with Ryuu-kun to boot! Partners forever, how romantic!
Now to sit back and wait for the moment when Chiquita explains that last fact to Karma, lol.
@HDMI1 I thought she was making a dig at Karma, since she is basically her parole officer and had to teach her things like "how to hug her son" (per chapter 5.1)
