Dear Bruce [British and American]

One day, the housekeeper found an unusual letter in the mailbox of Wayne Manor. The envelope states that the recipient is Batman, who lives in the Batcave, but the letterhead reads: "To Dear Bruce." These letters from unknown sources appear once a week, and most of them are gushing praises: "Hey, cool brother, you are the superhero who accompanied me in my childhood. I dream of being your Robin!" There are also some incomprehensible but informative comments: "Happy 80th birthday, Old Bat. I look forward to the restored version of the book appearing on the screen again, and of course Bell's classic Dark Knight image..." There were some angry curses and complaints: "Damn Tom King!! Brucie baby!!! Mom won't allow you to marry Catwoman, so stay away from her!! Isn't your SWB threesome a good one???" In addition to the guy named TK, the one who is most often targeted is also an unexpected person they know: "B, when are you going to beat up the shitty Riddler again?" Batman didn't intend to respond until he fully understood the cause and effect, until he received a letter indicating danger: "I have always regarded you as a role model, Batman. But, I'm sorry, this time I just can't stand it anymore... I can't see the point... I can't see the hope..." Bruce began to write a reply. Not all letters are named by Batman, but since they appear in Wayne Manor, they should be subject to Batman's review. "Dear Nightwing..." So Dick is going to be a police officer in Blüdhaven? "Lord Clown, I'm your fan! In TDK, you were so cool with the incomprehensible choice between two things you did behind the scenes!!" ... A black-box operation with no solution, huh? "NANANANANA! Batman!!" It seems like something magical has sneaked in... [The Superhero IP Planning Headquarters has opened a simulated mailbox. Fans can confide everything to their favorite heroes. If they are lucky enough, they may receive a reply from the staff in the voice of the hero himself. *Unilaterally breaking the dimension, fans do not know the true whereabouts of the letter. *In addition to handwritten letters, there will also be audio recordings and emails, and emails can have attachments. *The circulation range of letters will be randomly expanded to the multiverse, super heroes versus super heroes, super heroes against super heroes, etc. Please look forward to the tycoon group fighting each other across the air; Luther and Clark becoming close friends and pen pals; the four little birds passionately insulting Bat Black in a round-robin battle, among which a certain literary young man is the most spicy... Intention: Happiness is all that matters
