Ichigo felt a mixture of emotions as he received the invitation to Rukia and Renji's wedding. Despite feeling genuinely happy for his friends, a twinge of sadness and nostalgia crept in, reminding him of the adventures shared and how much their lives had changed since then, even if they were at each other’s throats all the time.

As he stood in his room, holding the invitation in his hand, memories of their battles, laughter, and camaraderie flooded his mind. He couldn't help but smile, knowing that despite their different paths, their bond remained unbreakable. Deep down, he also felt a pang of longing, realizing that this milestone marked another chapter in their lives, one where his paths with Rukia diverged further.
