I made a topic about it, next time I suggest you try looking in the first pages of the board for stuff like that.
Basically it's just a playlist of the 10 Valentine Day DLC missions so you can play them in one place, not sure if it has anything special in it.
Also while loading it from the loading screen (press Y before it locks in story mode) it caused a glitch that wouldn't let me customize options like difficulty, weather and time of day for some jobs that I hosted (tested on Coveted, couldn't change difficulty and weather). --- GT: xXDevilSpudXx.
