Kuroo rubbed his eyes, "And we're going to talk about why you think I would hit either of you." He mumbled, "..but..does he make you happy?" He asked quietly.
Kazuhiko was honestly afraid, he was shaking, "Y-yes..very much..I-it's like how you felt when y-you realized Kenma loved you..it's this overwhelming happiness. That when he's away it hurts so much sometimes, it's hard to breathe..a-and I know he's my brother..b-but dad..it's not fair.." he said covering his eyes, so nobody could see him Crying, "I-it's not fair that he's my brother..but, i-I've loved him forever, dad!" He looked at Kuroo, the tears were pouring down his cheeks.
Kuroo sat there for a minute, before sighing, "Kazuhiko, if you love him and he makes you happy, then..we'll support you." He said quietly, "I don't understand why by some sort of sick twisted fate your soulmate ended up as your brother. But..sometimes things like this happen, and you know I'm not good with words, but I knew this was coming." Kazuhiko's eyes widened as he tilted his head, "W-wait, how did you know this was coming..?"
Kuroo looked at him, "You took after me, yeah? You were constantly flirtatious and making up some horrible jokes to get other's to laugh, but every time Sachihiro came to visit, because you constantly persisted, they'd stop. And all your attention would be on him and you'd just get this look, of..like admiration.. like he alone was some sort of God that was given to you. And I had warned Kenma Of it happening, but we weren't sure when or if it may just be some kind of phase or if you actually loved each other. And well, now we know. But, if this is what makes you happy. Then, I'm happy." He looked At his son, smiling warmly.
Kazuhiko couldn't believe it..his dad, of all people, had..accepted them? His eyes welled up with tears as he lunged at his father, crying hysterically, "Dad thank you!!" He hugged Kuroo tightly.
