"I'm used to it," Kasane said. And those words embedded themselves into Atsuki's heart, causing him to regret and begin changing his own laidback attitude as well as resent his sister for causing such words to have ever come into existence. The entire manga (which isn't saying much) revolves around this one scene--it's implications and consequences. Unfortunately, even with this central theme, the manga comes across as very disjointed and thrown together. It tries and fails to be cute and heartwarming. It tries and fails to have engaging drama and memorable characters. While some of its concepts have potential, the execution was severely lacking.
