Touko-san wa Kaji ga Dekinai.

*Serialization of the original doujinshi with the same title* When Akari is sent to live with her mom's old friend, she's surprised to find that the hard-working Touko-san she's heard so much about is actually a reckless adult with no knowledge of housekeeping whatsoever! What's to become of Akari now that she's a highschooler with the world's most unreliable roommate?
