Either it's that, or it's Anon recalling the good ol' times before he snapped at Reimu's bratty behaviour. Though if that was the case, I think anon should had applied more discipline before going for abyuse, Abyuse is last resort punishment for non redeemable yu's, only if those were Anon's memories though.
The thought bubbles seem to trailing into the yu's speech bubble so I guess it was remembering/imagining the previous images. Or is that anon's speech bubble? Grrr.. can't tell.
So it was an abyuser dreaming he was a yukkuri-lover?
To be honest, I can relate to dream-anon. I have a cat that I have wholly failed to discipline. Complete shithead; reminds me of yukkuri far too often.
