I hum back in response, his words not really registering.

"Yeah, along with the other group members. It's an honour. I never did imagine that I'd ever sign a record next to JYP but here we are." 

This make snap my eyes back to him, mine widening in surprise.

"What?"

"I did say I worked in the music industry." He shrugs nonchalantly. 

"You did say that." I nod, "But you didn't exactly say you're famous." I narrow my eyes at him.

Suddenly the puzzle pieces come together. The static silence on the other line of the phone when I asked his name, him teasing me about living under a rock, his face seeming familiar, his dig at my music taste being too old fashioned.

I feel embarrassed. I pride myself of having a very high IQ but why the hell did I not notice that he's one of those seven young idols who have taken the country; heck, the whole world by storm?

I've seen this face plastered on Billboards in many districts of Seoul, on magazine covers of my co-worker, on banners promoting different brands...

"So now you've recognized me?" He flashes me a dimpled smirk.

"Um, not exactly. You're a part of that famous septet right? I can't quite recall the name–"

"BTS." He interrupts me, propping a hand below his chin to support it as he leans towards me.

"Oh." I think I resemble a fish right now; mouth open in an 'O' and all. He chuckles at my expression,

"You're surely old Noona. Do you even know any of the recent kpop group names?"

"Yah, I know SHINee... TVXQ!" I rack my brain to remember any groups after the 90s but I can't come up with anything else. It's a total blank and I hate it because I've never been this ignorant. 

"Oh yeah!" I snap my fingers together as I recall a famous girl group, "Girls Generation."

He shakes his head and mutters but loud enough for me to hear, "Five out of hundred. You fail."

"Hey! I've never failed in any test in my whole life. I'm very competitive you know?" I narrow my eyes at him again and he bursts out laughing.

"Sure, sure."

"I don't care for that patronizing tone of yours. Did you forget you're younger than me?" I arch my eyebrows and he smirks and leans closer, making our faces inches apart and me breathe in his unique scent. 

It's a rosy aroma, maybe even a hint of jasmine and I distinctly remember him telling me he doesn't like perfumes so he uses body lotion. 

"Three years is such a stupendous age gap." Sarcasm drips from his tone but his eyes have darkened and so have mine. 

However, the spell is broken when the sandy haired guy from before interrupts us with a subtle cough.

"Oh hey Mark!" Namjoon gets up to give his friend a hug. 

"Long time no see. You're always so busy." Mark complains.

"This cafe is always filled with customers and you know I can't just walk right in." Namjoon sighs a little.

 I realise it must be hard, being a celebrity and all. He can't meet his friends like a normal person would be able to, he has to go incognito while going out so that no one recognises him. 

"But you can always 'walk right in' for beautiful women, right? You even called and begged me to close the cafe for today." Mark wiggles his eyebrows and winks at me.

I see Namjoon sheepishly bite his lower lip and I am sure my face has reddened like a tomato.
