Valentine Eve's ...

——It's Valentine's Day tomorrow.
——Well, haven't you noticed that there's something special with the date?
——13th February, you mean Valenswine’s Day?
——Nope. Go look back to Internet slangs, especially which had been out-of-date for years.
——Got it! In Tieba, 213 means "2B" (=fool) .
——Bingo. But that's not what I wanna say - at today.
——?
——Today is Lin Jing's birthday! Happy birthday!
——...why he needs to wear high school uniform and pose in that way - on his birthday!
