This video is full of metaphor. 1. Notice that in the end his red string is connected to the girl we previously see as 'alien' through the guy's eyes. The girl is probably his crush, but since he just can't understand a girl's mind yet, he sees the girl as alienating (in other word, weird). 2. The school book he sees is full of the girl's picture.. Well simply it's because he can't concentrate enough. He keeps thinking of this girl he likes. 3. The girl chomping the guy's head can be interpreted to be the guy's frustration as the girl is consuming his mind (in other word, he's madly in love with this girl that he feels he's gonna lose his mind) 4. And what about the guy and alien girl becomes ghost? To me, it looks like they both have come to mutual understanding about their own feelings. The two latter dancing emphasized this point. They celebrate this small step by being happy. (Cheesiness alert) 5. The last scene, the guy and alien girl both got detention? Well, it definitely shows how the girl is not an alien. That's where the metaphors come from. She's just as real and humane as the guy could be. The thing they got to do together shows the beginning of this middle school romance.. lol What do you think? This is just my opinion.
A UFO with a red string attached to the bottom? K. The UFO abducts the random Asian kid? Alright. A hot Asian alien girl inhabits the UFO? I can accept that. The hot Asian alien girl turns her head into a monster and chomps his head off? Jesus christ, I need to stop doing these drugs all the time.
