So I just saw this post on Tumblr and I'm 500% okay with it potentially being they knew each other in the past and it's one of these things:

”I still have you in my phone under ‘don’t call’ even though it’s been years and I just accidentally sent you a rickroll oops” au

“this is so unfair there’s this song getting popular and the singer sounds like you and all these lyrics almost sound like they could be about me but you’re singing about lost love and you weren’t in love with me wait I’m watching the music video and crying and hey that’s definitely you wtf” au (this one is up in the air because I'm not sure how likely a celebrity would be living in not-Tokyo)

“oh my god i just hit someone with my car and it’s you hey i’m sorry are you okay please don’t sue?” au

“we’re romantic leads in a play and hey what ruined our friendship again OH YEAH THIS INSANE CHEMISTRY this isn’t awkward at all” au

“you’re famous and just got asked if you were ever in love this should be good– WAIT WHAT” au (see other note)

“so i know we just reunited but mind explaining how your whole life went to hell?” au

“you just liked a three year old photo of me on instagram i didn’t even know you had an account” au (this one is a potential, but Twitter is a more popular social media in Japan)

“something came up and now i’m really scared you’ll spill this old secret of mine please don’t do that” au

“i’m a nurse and oh my god what happened why are you here i can’t lose you a second time” au (I'd be willing to explore the "lose you a second time" aspect of this one, but Tsubasa is not a nurse.)

“did you know when you meet your soulmate ‘x’ happens? the government’s kept it under wraps but i just found out and i think we should try again cause i always assumed it was coincidence but that thing happened when we met” au (Just... no.)

“i’m moving and i know this is a long-shot but want my dog?? you’re the only other person it ever liked and i hate you but i love it” au

“i thought you hated me but i just accidentally sent you a booty text and you accepted and i am seriously considering it” au

“so i didn’t know why you dropped contact with me and i just found out and here’s how i totally did not do that” au

“we’re texting for the first time in forever and i told you about some stupid thing i did and sent a sarcastic ‘you must really miss me, huh’ and you just replied ‘yes’ and i think my heart just broke” au

“our best friends are dating you’re still the spawn of satan though” au

“i just found out through social media/mutual friends that you’re gay/bi/pan/etc. do you know how many times i did not make a move” au

“we’ve been chatting online and we get on really well and oh that explains it” au (bonus: i totally told you about my crappy ex oops it you)

The crossed out ones I may consider with a lot of convincing.
