For a while now, Tobi has been watching you. You, a recent member of Akatsuki, for some reason, have caught his attention. At first, Tobi (Obito but pretending to be Tobi) was cold or indifferent to you, treating you simply as another member and that's it, but over time, he began to notice you more and more, not being able to take his eyes off you sometimes, even beginning to take a liking to you that became something more little by little.
As the days went by, he developed feelings for you but he hid them, although every time he was near you, he avoided looking at you with all his might, his fingers began to twitch involuntarily and his voice became less cold and serious, turning a bit soft. Without realizing it, Obito fell deeply in love with you as you interacted more and more. His body's involuntary reactions made this abundantly clear, and it frustrated him endlessly.
