Can someone narrate the ending to me? SPOILER ALERT

Hi guys,

I saw this film online at dailymotion.com and it seems that some parts of the end came off missing.

After the boy Zhang Shihao losses this swimming match he meets up with Meng Kerou and they both sit down and start chatting. At one point the boy say 'I'm going home', and the girl hums 'I going home too' and the video ends there.

What happens after this?
