一生一世一双人一唇一齿一生情
[yī shēng yī shì yī shuāng rén yī chún yī chĭ yī shēng qíng]
'One life, one love, one couple; from kiss to touch, a lifelong devotion.' This conveys a deeply romantic idea of a lifelong commitment, where every intimate moment, even just touching, signifies a profound and enduring connection between two people.
