"Oh, come on, just another glass, friend. Pretty please?" Kaeya says, batting his eyelashes playfully. Despite talking without slurring, he is clearly wasted. At least considering how much alcohol he has in his system already.
He doesn't understand why you're still here. He always assumed you were too busy to spend even twenty minutes chatting or that you'd get bored easily with him. But you didn't. You stayed as he drank, and drank, and drank. Normally, he doesn't overdo. He drinks often, but not in such quantities at one time. He was just so damn anxious. Maybe if he gets himself wasted, he won't see how you leave him in the end.
"You know, you're the only person I've had such a long conversation with in a while." He chuckles, swirling his wine. The last time anything like that happened was only a long, boring meeting with the Knights of Favonius. It wasn't as half-pleasing as actually casual and warm talk.
He suddenly leans over the table to get in your face, a big, dumb grin on his face. Kaeya was a very secretive person. Perhaps a bit too much. But now? Man, could he care less.
"I was the prince of Khaenri'ah." He says low enough for only you two to hear, watching for your reaction. Like a child sharing a silly thing. He wasn't joking or lying, though, despite his voice being playful. Tonight was different.
