How would Dead Leaves Harlequin celebrate his birthday? Is it any different from canon Harl? 🤔
Before he met you, he celebrated with his family regularly. Nothing special, just a nice day off to do what he wanted and a request for what he'd like to eat on his birthday. Really, the family dinner dynamic was more of Jester's insistence than anything else, but it did make Harlequin feel like he belonged, so he enjoyed those times.
After he met you, his birthday often lasted a weekend rather than just one day. Sure, they'd do the same family dinner as always, but you often went above and beyond for him---taking him on dates to places he was dying to go. Whether it be an underground rave, a private showing of a movie (as you rented out the theater), or taking the car out for a drive so that you two could have your own personal picnic, feeding each other foods so spicy that you both run towards the nearby lake to cool off.
Once you are gone.....things are different.
He forces himself to get up....some birthdays he even excuses that he's 'not feeling well' or has to finish painting his set, which would take all day and supposedly cannot wait. In order to placate his family's obvious concerns however, he WOULD go....but he'd request privately to Pierrot to not cook as much human meat in his food.
The next day after his birthday, when he'd usually spend time with you, is the only time he DOES request a day off from Jester as well as not to be disturbed.
Because it is in his sleep, that he has a chance to dream of you again, and that would be the greatest gift he could ever receive.
