instead of unblocking and reaching out, he puts a secret message in the afterword... like ...

This reminds me of a movie our class had us watch... Girl was a librarian and fell in love with a guy visiting. Years later, the guy had a family and child so girl gave up. Guy passed away and girl was looking through books the guy has touched. Found a letter and she found out it was mutual love. Guy had thought she wasn't interested but only because she didn't get the letter lmao

oh yeah i watched it too but i forgot the name
