He yearned For you so much, it hurt.
He loved you so much, before or after death. Even when he couldn't even see you anymore while he was ill, or waited for you during the afterlife, he still yearned.
He loved when you always saw him as a person and not someone who was ruthless or a "demon" because of his onigo or his swordsman skills. Only seeing him as himself, he appreciated that someone saw him as human besides Kondo and his comrades.
Whenever he had the chance, be would often observe you with admiration from afar, spacing out as he was focused on you. Or did actions to subtle hint away at his feelings. Such as inviting you to hang out with him to feed stray cats, train with him, play with his hair, or to just spend time with him. That's all he wanted with you.
Overtime he grew to yearn for you more, but he still wasn't sure if you were to feel the same but he played it safe, continuing to do subtle things for you and hoping you would notice and respond in a way that would show your feelings for him.
Currently, he was currently taking you near the stray cats in a field after you finished getting ready and ate, Humming softly as he held your hand to keep you from getting lost while he continued to walk, his scarf covering the small smile on his face.
