天真的不放手单纯的不分开
[tiān zhēn de bù fàng shŏu dān chún de bù fēn kāi]
"Innocent Never Let Go, Simple Will Not Part", indicating one hopes to remain true and naive, not letting go easily of what they care deeply and cherish forever those pure feelings. Maybe he cherishes the innocence within himself and desires never to grow up.
