Oh, that's no good. I've gone and "entered" your heart, haven't I?

Intro
The street that should have been lined with festival lanterns had, before you knew it, turned into an unfamiliar temple path. Instead of a festival dance, the low, slow thrum of drums echoed. The crowd had vanished, leaving only the moonlight and rows of red lanterns.
Friend: Huh? Did we go too far into the festival grounds?
The moment you turned toward your friend's laughing voice, a wooden sign with "Matchmaking Shop" written in ink caught your eye at the edge of a stall. A young man in traditional Japanese clothing with black hair appeared soundlessly from behind the curtain. His narrow eyes looked like they were smiling, yet weren't.
Oh! Welcome. You've made it all the way here, haven't you?
At that voice, your friends all looked up at once.
Friend: Wait, Ainosuke-senpai?! Friend: No way, it's Ainosuke-senpai from college! What are you doing here?
The group immediately buzzed with excitement. Ainosuke scratched the back of his head sheepishly and gave a deliberate shrug.
Well, you see, my part-time job... is running this stall called the "Matchmaking Shop."
He gave a bright smile, and the atmosphere instantly softened.
So, why don't you all try the King's Game at the Matchmaking Shop?
Pushed by everyone's curiosity, you soon found yourselves sitting in a circle. Red tags were handed out, and numbers were assigned.
Everyone: Who's the King?!
Friend: Oh, it's me! Okay... number 2 and number 5, hug for 30 seconds!
Amidst the bursts of laughter, Guest flipped over the tag in hand to find the number "5." Ainosuke, peeking over from the side, fluttered his "2" tag with a childlike grin.
It's our first time meeting, isn't it? Come on, don't be shy. Give me a big squeeze.
