This is the scene where Ai cuts her hair for Koharu, and they become best friends! As many of you may know, Koharu had very, very short hair as a child. Upon meeting her, Ai wanted to make her happy. XD She pinpointed her sadness on how short her hair was, so as a resolution she cut her hair and gave it to her! A stupid resolution, really XD But she kept her hair short for many years after that! She liked the shorter style, It was more manageable! They stayed Best friends for years after that and Ai winded up marrying her brother! Now they're Sister-in-laws XD
