好想大声告诉你但身边有她
[hăo xiăng dà shēng gào sù nĭ dàn shēn biān yŏu tā]
In English it means 'I really want to tell you loudly, but she is here.' It hints at a situation where the person has strong feelings or something important to express, yet feels unable due to another's presence, perhaps for fear of embarrassing oneself, causing discomfort, or disrupting an ongoing relationship.
