So, I watched some Nyongtory fanvids and I shipped them now haha
Anyway, I got this crazy interpretation of LOSER MV GD SEUNGRI SOLO becoz of it

Let's talk about GD first. He looked around once he entered his place, like looking for someone (Seungri?) But there's no one there. Meanwhile Seungri was watching couple walking around, the thing he couldn't do w/ GD because paparazi are always all over them.

Then GD watched black and white cartoon with 2 characters on screen, somehow reminds me of Tom and Jerry (it's describing Nyongtory, right? Since at some point they said they're like Tom and Jerry). GD started to break things because he was tired of lying to the public about him and Seungri. The tattoo on his neck 'Truth of Dare' describing himself debating whether to tell the truth of just let the thing like now (people thinking he's and Seungri are giving fan service). GD looked at the eyes poster in front of the building thinking it's all the judgemental eyes he and Seungri had to face if he came clean to the public. 

Back to Seungri, I think he got an idea to make the girl helped him. I think the girl was like pay-up girlfriend or something. At the end Seungri asked for the girl's help to maybe 'play' GF w/ him to cover up the public from the one he truly loves (GD). He tried to call GD about his idea. Yet GD was busy looking at himself in front of the mirror, deciding to hide his real feelings again, like so many times. He began to ignore Seungri's call because he didn't know how to face/talk to him. Seungri lashed out and began to throw things as he couldn't find or reach GD. Both of them were so exhausted.

In the end, GD wondered around nowhere. Meanwhile, Seungri's plan failed and the girl was mad or maybe bailed at him. GD ran into the street with no care about the world and then sat down in front of a sign. It was written 'Do Not Enter, Wrong Way'. It probably described his situation. He loved Seungri and vice versa but their career and life would doom if the public knew about them. It's but they had to live with it since they loved each other so much. So that's the end of my conspiracy theory.
