@Quartapple Good call-out, but more than just that. When Yuu told her that she looked like her dad and her sister looked like her mom she wasn't shaken.
Being told "you're not like your sister" was a trigger point in the past, but now it's a truth she can smile at. The growth is real here.
Came back to reread this whole manga again and I still believe it’s one of the best. This chapter had a lot of emotion especially with the monologue and I adore them both so much. This is a very heartwarming story.
