Someone help me figure out what this song is?

Well a few weeks ago I listened to this song that my cousin showed me of a guy who keeps following a girl to wherever she goes and asking her to be his lady. At the end they're on a plane and their whole class is there and is singing that song?

Help me please.

 

You mean this is the video..or this describes the lyrics? ö_Ö

 

I'm also looking for this song and it's the video.

I think the song goes something like ''Oooh Ahh, I love you Ooh Ahh''. Although I'm not sure I got the spelling right :/

 

I have no idea what that could be, but you should just ask your cousin if he/she remembers what it was called.
