Pretty sure incest tag should be removed. Last page has her saying "we were childhood friends in the first place" so she's either a sister-in-law or he's using the term onee-chan in that more general manner of addressing close female acquaintances.

@face1355: I didn't add the incest tag myself because it's difficult to tell if it's appropriate.
In part 1 they show that Yuuta is raised by his neighbors after he lost his parents, but it does not explicitly state that he is adopted. IF he is adopted, the incest tag would count. (Tag description: "Sex involving family relatives, even those not related by blood.") He probably is, but we just don't know for sure.
