It'll be up to you whether or not your character participates, yes. I'm not going to put together a list of who's with who. Rather, it's going to be a matter of choosing that your character go through with something that will make them more prone to participate.
It will not be mandatory and will not be aggressively lewd, though it will be great!
I see it running the 14th-16th OOCly. We can do a timeskip to after the mission if need be for the thread to take place in. I hate doing that, but it may be necessitated in this circumstance. If a timeskip is indeed necessitated, we will continue the mission and wrap it up at its own pace while doing the love day thread, which will occur on the 14th ICly.
I will not be starting the thread, so keep your eyes out for a new thread and post in OOC about it on the 14th!
Also, sorry for the long explanation. Even though I diatribed, still feel free to ask questions or raise concerns about it! Love is a fickle thing, of that I'm aware.
