生命的每一秒爱沵心跳的每一次想沵
[shēng mìng de mĕi yī miăo ài mĭ xīn tiào de mĕi yī cì xiăng mĭ]
Translating directly, this username is quite romantic, expressing that love occurs in every second of life and heartbeat yearns for 'you'. Note: '沵' here is an alternative character for '你' which means 'you' in English.
