Help me find it, please!

First off, if this isn't the right place for something like this, I apologize and accept any and all responsibility/punishment.

 

Now then, for why I even made this thread.  Some years ago I was reading this manga that I had to stop for various reasons.  Now that I have the chance, I'd love to read it all the way through.  Problem is, I can't remember the name...  I remember what it's about, but that's it.  That's why I'd love for someone to read what I remember and try to tell me what it is.

 

It's a romance type, only not a traditional type.  The story is that in order to combat declining birth rates, Japan has set up this system where once a year everyone that is 18 gets together and gets sent on this camp/retreat sort of thing in order to try and find the person they are to get married to.  The folks are divided up into groups with equal male/female where they stay and live/work for a time.  During this time they are divided up into boy/girl pairs for their various jobs.  This whole system has become so successful, that the people of Japan have gotten to where they believe that if a couple gets together outside of this program that they are not true lovers and will just break up later down the line.  Also, those that go to the program and fail to come back engaged(that's how you leave the program early), you are essentially a waste of a human.  As for the actual story(the group that it follows), I left off where the protag and the heroine uncover a plot from one of the girls to decline any proposal, which makes the rejected one move to a new group to try again, until the man that she was in love with is shuffled into her house.

 

That's essentially all that I remember from it, and I'm sorry if it's not enough info to go on.  But thank you for taking the time to read this, and possibly even giving me the title that has eluded me for so long.

If you still need help finding this manga

Quick question;

Is the manga exclusively revolving around one couple or are there multiple arcs/chapters based off other couples?

[Mistearea]

I'm not sure.  When I had to stop reading it, it was on the same group that it started out with.  And even back then, when it was still ongoing, there were quite a few chapters I needed to read.

Well to be honest I don't read manga much but I may be able to assist you in finding it, try Happy Project.

That's it exactly!  Although I could have sworn it was much longer than that.
