心深似海藏少年c
[xīn shēn sì hăi zàng shăo nián c]
This username conveys the sentiment of hiding deep and lasting memories or emotions of youth, particularly cherishing a teenage sweetheart. The 'c' at the end might indicate that this feeling has been concealed ('c' possibly meaning 'conceal' or could be arbitrary). It implies nostalgia and hidden passion.
