10 years pass but Yoona still remembered the young man. "Yoona, hurry up you're gonna miss the concert," Taeyeon said, Taeyeon is Yoona's best friend.

"Who's concert are we going to again? "

"EXO's silly, now hurry up."

"Ok, ok. I'm done now."

"Ok let's go now. "

"Ok." Both of them arrive at the concert, EXO is singing Growl. Later, it's D.O's part, Yoona recognized him immediately.

"Taeyeon, who's that?"

"That's D.O, he has a very good voice. Why do you want to know about him?"

"He reminds me of someone." The song ends, EXO leaves.

"Wait," Yoona ran after D.O. "Yoona, wait up!"

Yoona bumps into someone," I'm sorry," they both said together.

"Wait, can I ask you something, D.O, right?"

"Yes, I'm D.O."

"Good, do you know who I am?"

"My fan?"

"Yes, but no, but 10 years ago you beat those people who bothered me." D.O was blank.

"I'm sorry, but I have to go."

"Wait, just a few minutes please." Yoona started crying.

"Maybe you're not the one I'm looking for."

"Don't cry you look prettier when you smile."

"That's what he told me."

"Well since you think I'm the guy you're looking for, give me your phone." Yoona gave D.O her phone," there, call me if you find the guy or if you can find a way to make me remember about your past."

"Ok. Thank you! ^v^"

"I have to go now, bye!"

"Bye!"

"How do I make you remember me?"
