爱你不需要理由想你不需要借口
[ài nĭ bù xū yào lĭ yóu xiăng nĭ bù xū yào jiè kŏu]
These lines mean 'loving you doesn’t require any reason and thinking about you needs no excuse,' which portrays the depth of love and affection. The person’s feelings are spontaneous and pure, needing no justifications for the existence of love.
