Who's that? Is it really MokouKeine? Its kinda strage to see them reversed :)
MariAli would suit the story better though

Nice to see Mokou x Keine getting some comedic love. A lot of Mokou doujins are pretty dramatic (for good reason, she has by far the saddest life of any Touhou character), so it's good to see some lovely dovey blush heavy comedy once in a while. This and Moko-love by the same author are very nice, although I would have to say I find Moko-love to be the better of the two.
