22 !
Gangrape.
2+2=22 which is the age you try to experience everything you can while you are young, and you begin reading and doing many things. After trying everything, you stumble across manga, something you would bully kids for reading when you were 13. Now you try it, and along the way find many genres, one of them being yaoi. Something you can't forget, because when reading it, you are taken into a whole new universe. Just like reading fantasy, but in a much much different way. As growing older, your love for yaoi grows also. So now at age 27, you still read yaoi, a genre of manga you found at age 22. The number 22 split in half is 2 & 2 . After adding them back together, you get that golden age. So, 2+2 technically, equals yaoi. Because, after trying everything out at 22, yaoi is something that stuck. You are welcome lmao
You fuck things up at age 22 like starting to get addicted to reading yaoi out of curiosity. Why 22? Because 2+2
A summary.
What is 2 + 2?
