Since the 50s, songs have become longer, from an average of 2.36 minutes to 4.26 minutes this decade. If you want a hit, it may be best to stay away from writing ballads â ever since the 40s, the average tempo of chart entrants has hovered between 117bpm and 122bpm (ballads usually play at around 90bpm).
Sesshomaru doesnt fall in love with rin, she is like an adopted lil sister to him, he protects her like a big brother to his lil sister.
And in the case that a child would not be in the picture, the way I view the affair between Sesshomaru and Rin's is that of a Father-Daughter one. Sesshomaru takes care of Rin, and he certainly cares a great deal about the girl but that doesn't necesarly mean he'll fall in love with her or that he is in love with her.
