Summary[]
At home, Ruby notices Aqua reading books and gives him a hug but Aqua complains that her hair is tickling him. Then he says that her hair is more silky which delights her. However he also suggests her to tie her hair as it is a nuisance having them loose at home which annoys her. She storms out the room which leaves Aqua confused.
Ruby recalls that in their previous lifes, Gorou once mentioned to Sarina that Ai's charms lie in her silky hair.
Aqua then remembers the exact same conversation and so the following day, he makes up by drying Ruby's hair after her bath and compliments her long hair.
