魔笔抹不去的回忆
[mó bĭ mŏ bù qù de huí yì]
The name suggests that some memories remain deeply imprinted no matter what. The phrase uses the concept of a 'magic pen'(a common literary device in Chinese culture referring to brushes or pens capable of extraordinary things), indicating some memories have such a profound impression they cannot be erased even with magical power. This might allude to particularly poignant or powerful past experiences.
