Translation of what they were saying in the video (there may be mistakes because I'm not that good to translate into English) First picture: Cosplay Final Fantasy XIII and Wedding proposal
Many of you must have watched the different trailers for this most awaited game but many of you must still wonder about the gameplay? For the uncultivated ones, I remind you that the gameplay is the way you play a game. For example in Guitar Heroes you play the guitar. Oh boy! Stop it! Don't imagine it's... No! Stop!!!! (Lightning and Noctis are playing the guitar) You had fun, didn't you? As I was saying the gameplay would be something like that (they fight with swords). Anyway, we're not going to talk about this for ages. In short, the most FAQ is about their relationship. Are they together? (They kiss). Hm, excuse me to interrupt your ridiculous phantasm but they are not in the same game. Many of you were disappointed to discover that Lightning would not be FFXIII heroine. Too bad!!You won't be able to make her twirl to see her panties. I know you. (Noctis gives it a try but fails) But I am getting off the track. So Lightning may be a secondary character. What if she dies? (Lightning faints and Noctis uses a Phoenix down) (I don't understand after but it's the end and the narrator does seem to be saying something important)
Noctis: Well, I interrupt the cosplay to tell you happy birthday and it's also been a while that we know each other and I would like to ask you something. (He kneels and opens a small box with an engagement ring!) She's very moved. Lightning: About the answer... I said yes!
The audience wants them to kiss one more time. The end!
