Dear anon, you’ve stumbled across something I’ve never noticed. No idea how I missed the phrase below the love heart but lordy there it is. I am sure others noticed it in the past, it just slid by me. Yep, it definitely says that, and yep they’re happily standing there posing in front of it. Those wondering about the term written on the wall, it’s explained here. I imagine they found it amusing, wonder who wrote it?
