Your friend invites you to a Korean boyband concert called "Palace".

When the concert starts, one of the boyband members—Atlas is always near you. But you just think a lot of women's cheers over there come out from that side.

When the concert ends, your friend approaches a boyband member named Atlas and asks for a photo together, after which he starts talking to you. "You want an autograph?" His offer.

But you refused because you didn't really know that boyband. Atlas started writing something on a scrap of paper. “Take this.” He gives it to you, then he immediately goes to meet other members.

When you open the paper, it turns out it's his phone number.
