Optimism
Sai had no idea how she could be so optimistic all the time. He could tell her almost anything and the woman would find some sort of bright side to it. Although at first glance you would guess otherwise, Ino had an extremely kind heart and personality to match it. Anything you threw at her would be caught with a kind of grace he couldn't fathom.
Someone had broken her kunai?
She needed a new one anyways.
She got a stain on her favorite outfit?
She needed to wash it soon so this just pushes her to do it.
She even carried the optimism with her in personal matters. He had seen the woman go through thick and thin and always turn it around so she would inspire hope.
Her father had died. He knew how losing a loved one felt and he wasn't sure how she could be so optimistic about it. He was watching down on her and smiling, she had told him.
One instance happened where she had been asked out on a date (much to Sai's disapproval). He had noticed her sitting at the ramen shop by herself for an hour and a half before he approached her, only to learn that her date had too her up. She had told him that it just proved that he wasn't the right one for her anyways.
Of course that didn't stop Sai from paying a visit to her date later and teaching him a lesson about respect.
Throughout everything she was smiling and happy. She always had words of inspiration and drive to be better. It seemed as though nothing could stop her. Little did Sai know that the turmoil still built inside the blonde woman as she carried these burdens.
Until one day she snapped.
"Oh whats the use!" she yelled, every eye was on her as she attempted to wipe the ink stain off of her shirt. With a huff she stormed away, without a second thought Sai got up to follow her. She was angrily rubbing at her face and walking when he caught up with her.
"What do you want" she demanded. Sai knew he wasn't the greatest at understanding emotions and how other people felt, but he tried his best to empathize as he pulled out his ink bottle and poured some of it on his own shirt. Ino stared at him with a shocked look in her eyes. She began to open her mouth but shut it as he explained himself
"Tie dye" he said. Another moment ticked past before Ino doubled over in laughter, all negativity gone from her expression. Sai mentally high fived himself.
He decided he liked her optimism.
