我孤单成性思念泛滥我疼你爱你绝不二心
[wŏ gū dān chéng xìng sī niàn fàn làn wŏ téng nĭ ài nĭ jué bù èr xīn]
'I am habitually lonely and overwhelmed by longing for you; I will care for you, love you, and remain true to you.' This reflects someone who feels frequently lonely and has an intense longing for a loved one, along with their commitment to loving and caring only for that person.
