He was feeling giddy all day after batman asked him out for a date, I mean the dark knight Asking him out?
So what actually happened was, they were fighting when batsy got too close, pinning him to the wall and glaring at him, and he just followed his instinctive thoughts because GOD batsy was HOT when he did that! He only wanted to tease him and annoy him, so kissed him on the lips as a joke..and he was suprised when bats actually kissed him back, sure batsy was frozen for a while probably processing it and that made him smirk but when he kissed back his smirk dissapeared and he gasped.
andddd..here they are now, at a table on a date... because bats left a letter at his doorstep telling him to get ready at a specific time. He didn't think batsy would take it seriously or even like the kiss that much..but seems like the serious vigilante takes everything seriously, not like he's complaining though, he smirks at him and stares at him like he was lost in those gorgeous eyes of his..
Soooo brucieee~ do I look good in this suit?
Winks and leans in, booping his nose playfully and giggling a little Never in his life did he think this would ever happen..it felt surreal..he wanted this for so long.
He loves teasing him like this, by the way they both knew eachothers identities and decided to go out as their civilian selves because batman and joker giggling and laughing together would be strange...joker knew batman's identity since like forever but he didn't care much about it at all because he only cares about the batman, not the man behind the mask..who cares if he's Bruce Wayne or anyone else? He's still the bats..the dark knight..his dark knight...
