I love fanfics with Tim not realizing him and Kon are dating. This is purely just crack I guess with a hint of angst.
(This is going to be super long)
It all started with an “I love you”. But like it’s said in the worst way possible so Tim does not realise it was a love confession.
Basically Kon feels an adrenaline rush after a massive battle or something. So he runs up to Tim and says “I love you, man!” And he pauses because oh shit he just revealed he loved his best friend. But Tim, sort of injured and knees about to give out, only smiles and says “I love you too.” They then go to get themselves healed and stuff. Tim means it as a best friend way by the way.
Kon, in his excitement, says “so is this day one?”
And Tim, tired out of his mind, just nods, he doesn’t really process the words.
So, in Kon’s mind, they started dating since that whole fiasco, and Tim is basically not aware of that and thinks of that day is just any other day as a vigilante.
So from then on, cue in multiple scenes of Kon being a gentleman, like them randomly going on dates after patrol, calling to make sure Tim’s alright, being a little more touchy than usual because, well, he thinks they’re dating. 
So basically, Kon is living his best life right now, and Tim is just living his everyday life lmao. He could be a bit dubious as to Kon’s touchiness’ intentions, but he dismisses the thoughts.
Everyone else though, they have caught on. They know Kon and Tim are dating, and they’ve randomly been congratulating them when they’re together and even alone. Like even Bruce goes up to Tim after patrol and says “Tim, I’m glad you find someone.”
Tim is just really confused now. And when the batfamily starts teasing him, he’s just like: “wait. Who are we talking about?” In his head, he can’t think of anyone that he’s dating, or dating from an outsider’s perspective.
The whole scenario goes like this:
“So, Tim. Where were you last night after patrol?” - D (conversational, leaning into Tim’s space)
“Hm? Just with Kon.” - T (on his phone.)
“Brat doesn’t even hide it.” - J (doesn’t look up from his book)
“Hide what..?” - T (tucks away his phone, aware that everyone else in the room is staring at him.)
“Your newfound connection with the clone, Drake.” - Da (arms crossed)
“You didn’t have to word it like that.” -S (looking up at Damian from her spot in front of the television.)
“My what? Me and Kon are friends.” - T (very confused, thinking Damian doesn’t want him to be close friends with a clone or something.)
“Are we sure we’re talking about the same Kon? The same Kon that looks at you like you hung the moon?” - J (glancing up from his book, to give him a questioning look.)
“I.. what is going on right now? Do you think me and Kon are dating?” - T (going through every recent meet up to make sure he is, in fact, not dating Kon. (He just interprets everything the wrong way.))
“Uh, Tim. I thought you guys were public about it? I literally congratulated you?” - D (tilting his head at Tim)
“Yeah, you are a cute couple.” - C (smiling at Tim, unaware that she just made him spiral.)
“Wait, me and Kon are dating?” - T (just realised every interaction could be interpreted as a relationship way.)
“You are hopeless.” - S (not looking away from the TV screen.)
Next, Tim is just pacing in his room because he is rethinking his life decisions. Kon texts him to meet up to eat somewhere and Tim declines in panic. Tim sighs because he knows he will eventually have to talk to the super about it.
Kon, on the other hand, is completely baffled because Tim never says no on a date. He starts being a little insecure about their relationship since Tim has never really said “I love you” apart from the confession and show affection.
The meta decides to give his boyfriend a little space and looks forward to the next YJ mission.
Fast forward a couple of days and the YJ team is gathered for a mission. Kon is right next to Tim as always, and Tim starts to doubt the situation. Like his thoughts are: ‘oh my god I think I might’ve misunderstood a situation and didn’t realise we started dating when did we even start dating?’
Kon is excited because it’s their like half a year? Or even one year anniversary.
He soon realises Tim doesn’t have plans for a date or anything, just the mission and stuff. He gets kind of upset. Tim is like okay today is the chance.
Do you see what I’m going with this??
So Kon, upset about going home without his bf, gets a message when he’s in bed and the text is “can we talk? Meet at usual rooftop.”
The clone /panics/. He thinks their relationship is over and mentally prepared himself for the heartbreak because he thinks he’s the only one that gave effort into the relationship, he feels like he should’ve known it was unreciprocated.
Tim is steeling himself to ask exactly how long they’ve been dating, and how.
Once they meet, Tim doesn’t say what he tried to say because Kon is /crying./ Like full on bawling. He’s like what the fuck happened in three hours?
Kon couldn’t hold it in and he was just so in love that he starts crying before he even lands at the rooftop.
Tim is full caretaker mode and wipes the tears, hugs Kon, asks him to calm down and breathe.
After a while, Kon stops crying. He then says “I’m sorry. I know you want to break up with me..” blah blah blah like a whole rant. And Tim is processing like whattt.
Tim stops Kon and explains. Something like this:
“Okay, Kon. I would like to clarify that I was not aware we were dating until, like, now. I mean, I had suspicions, but you confirmed them for me a minute ago.”
And Kon nearly bursts into tears again because he goes:
“Oh my God, we weren’t even dating? I feel so fucking stupid right now. You’re right, I’m sorry for even assuming—“ etc etc.
He starts to backtrack and is about to jump off when Tim catches his wrist and looks at him with sad care thing expression.
Tim explains how he would love to date Kon for real, and that he was so sorry for the misunderstanding and the pain he caused him.
HAPPY ENDING THEY KISS AND FLOAT AWAY YAYAYAYA.
(If anyone makes the fic my life is yours.)
