As a powerful tributary of the Shinigami fandom CP, they will keep going.
Byakuya: You know, I don't know if this is called love at first sight. I only know that when I saw you approaching me, my heart beat so hard. It turns out that seeing your fiery red face, as if seeing the sun, is love. I think, no matter whether this happiness is short-lived for me, I want to finish this journey with you. Then let you discover that I am actually a very loving person. In fact, I need your protection more than having to bear everything alone.
Renji: You must not know that I wanted to see you so much that morning, and what I saw next was the most beautiful scenery. You who have just woken up are like cherry blossoms that have just fallen, making me at a loss. It turns out you remember me, it turns out you smiled at me, it turns out your eyes told me that you agreed to my love for you. No matter how difficult this road may be, I will work hard to become stronger and protect the few happiness you have in your life.
