伴你99爱你99
[bàn nĭ 99 ài nĭ 99]
This nickname signifies deep commitment and love. The number '99' is often used in Chinese internet slang to represent eternity or a very long time, as it sounds similar to the words for 'eternity' (久久 jiǔ jiǔ). So 'accompany you 99, love you 99' implies a promise of eternal love and companionship.
