I have this head canon that H&L have made a little video every year on their anniversary.
“Hi, today is [insert month] 28th 2011 and we’re celebrating our first anniversary together, hope we can share it with you soon!”
“Hello, today is [insert month] 28th 2012, two years now, still here, see you soon”
“Hello everyone, here we are, [insert month] 28th 2017, celebrating 7 years together, still happy, still going strong, see you next year”
One day they will edit all the videos together and release them
