想念你慢慢变成我德呼
[xiăng niàn nĭ màn màn biàn chéng wŏ dé hū]
It seems the phrase tries to convey something like 'I miss you, slowly transforming into my virtue,' however, this statement appears to include a nonstandard expression (德呼 - virtue call). This online name might suggest someone missing another person profoundly and considers the emotion of missing them as part of who they've become in terms of character.
