The pairing between SHINee's Taemin and EXO's Kai. Take the 'Tae' and the 'Kai' to form 'Taekai.'
If they happen to be at the same event, one will find his way to the other no matter what it takes. They are often confused as a couple and neither has outright denied or acknowledged it. Instead, Taemin enjoys revealing nearly everything that happens between them, with or without the intentions of making everyone suspect that they're more than friends.
A: Did you see the way Taemin tiptoed and closed his eyes like he was going to kiss Kai?
B: Yeah. When will Taekai accidentally kiss?
