深知他是梦却不愿意醒
[shēn zhī tā shì mèng què bù yuàn yì xĭng]
This username conveys the sentiment of being fully aware that someone or something is illusory, a 'dream' so to speak, but still choosing to cling on to it without wanting to face reality. It reflects an unwillingness to awaken from what could be an unrealistic love or fantasy.
