OMG, OMG, OMG.
How do I apologize to an anime character? I've wronged, wronged, wronged Rikka's mother. Rikka ran away from her not the reverse! That scene with her delivering the bento almost broke my heart.
The confession scene was one of the absolute best and the ending just a shock. Yuuta you gave her the one thing that she needed to allow her to face reality--you.
