心跳你到底还在吗
[xīn tiào nĭ dào dĭ hái zài ma]
Translates to 'Heartbeat: Are you still there?'. It's asking in a figurative way whether another person still cares or has feelings, using heartbeat as an indicator of the presence or condition of one's emotions, thus expressing longing or questioning over lost or uncertain connection or affection.
