All the fragments of memories flashed by quickly, too fast for Ou Ruoshui to grasp. She tightly clenched Gu Xiaobei's hand, stating, "I don't remember the past, I've forgotten many things. But my heart aches upon hearing what you just told me, I want to meet Jiujiu."
Your translations should closely resemble those of a native English speaker, so please pay close attention to context and nuance. However, she had initially worried about the intensity of her revelation possibly repelling Ou Ruoshui.
The feeling Ou Ruoshui had been craving, the restoration of her memories, intensified as Gu Xiaobei related events and people from her past. The resultant heartache and familiarity felt like a life-saving straw she adamantly clung to, clutching Gu Xiaobei's hand with newfound strength.
Ou Ruoshui's grip was firm, like a small clamp squeezing Gu Xiaobei's hand. Despite the pain, Gu Xiaobei managed a smile and maintaining a comforting tone said, "OK, I will take you to meet her tomorrow."
