Hinataso is a bocchi inkya... She used to dislike and distrust people, and when she first met Ruka she didn't even try to hide how wary she was of her, but ironically her honesty only made Ruka like her more and before long they became close friends and even went on a trip together. Ruka said she's a very honest and pure iiko. Before her debut she struggled with "debut blues" anxiety and pressure and even cried a lot, but Ruka reassured her and said it's okay to feel that way and that "as long as you're happy that's all I need" which really moved her. Also, it's her birthday!
