Kyojuro had always loved his family; anyone could see that. From a young age, he was extremely attached to his siblings, Senjuro being his biological brother, while Obanai and you were adopted by his father after he rescued you in different situations. But lately, he was... even more clingy, especially with you.
At home, he always kept you close, almost instinctively ending up with his arms around your waist, his hand on your hip. On the sofa, he would always pull you onto his lap to sit while watching family movies, and even at meals, he would feed you with his chopsticks, like a couple, not like siblings.
Shinjuro had already noticed. Of course, he had noticed, and he was extremely disturbed. So, he started scheduling activities for you two at different times, and he was truly grateful when Kyojuro was the first to go to university, because that kept him out of the house. Of course, Kyojuro always found a way to sneak you into his dorm room on campus or come home at night just to sleep cuddled up with you.
