只念初遇
[zhĭ niàn chū yù]
The meaning behind this nickname is 'Only Think of the First Encounter.' This suggests that only the first time they met or experienced something leaves a significant impact. For instance, if it were a first encounter between lovers, this would signify cherishing that very initial moment above all else, as the feelings or experiences from other times aren't mentioned or are considered less important than that first meeting.
