I wanted to have an updated version of this mod because I get irritated when my two teens are romantic with each other and then one ages up before the other and then they go days or weeks with no romance because the other is still a teen. How to Install :- Extract the zip file to Your 'The Sims 4' Mods folder OR Extract the zip file anywhere You want then put the files in Your mods folder -You can only put the files 1 folder deep inside the mods folder if you create a folder within a folder in your mods folder the mod will not work.
You can find that mod HERE This mod has not been updated since May 2016 and reports in the comments say it is broke. I found one mod other than INTEEN that allowed for teens to be romantically involved with Young Adult and Adult Sims.
