久违心始偏袒于你
[jiŭ wéi xīn shĭ piān tăn yú nĭ]
'久违' means 'long-lost', conveying after experiencing long partings or waiting periods, '心始偏袒于你' means the person’s affection starts to have favoritism towards 'you'. Thus, expressing the feeling of having been separated for a long time, there now lies affectionate preference.
