别深拥只是梦
[bié shēn yōng zhĭ shì mèng]
This nickname '别深拥只是梦' translates to 'Don't hold deeply, it's just a dream'. This suggests the user feels that some relationships or moments of intimacy should not be held onto tightly because in the end they might turn out to be ephemeral or illusory. A rather bittersweet or cautionary sentiment is conveyed here, hinting at the impermanence and unpredictability of emotions or attachments.
