Akaneiro ni Somaru Saka

Junichi Nagase helps Yuuhi Katagiri when she is harassed in the street, only to ruin their next meeting with an impulsive mistake. Discovering that their parents have arranged their engagement makes the awkward reunion considerably harder to escape.

Yuuhi moves into the home Junichi shares with his sister Minato so the prospective couple can find out whether they can get along. School friendships and household routines draw them closer, but affection does not follow the tidy arrangement their families planned, and feelings within the house become increasingly difficult to untangle.
