'Sana?'

Tzuyu couldn't move her gaze from the president girl. Sana had her hands around the boy's neck while the boy's hands on her back. They didn't notice her.

"Xiumin, let's go."

Jeongyeon's voice finally could break Tzuyu's shock state. She released a breath, forcing gaze away.

"What's wrong? See ghost or something?" Momo asked as they approached stairs.

"Huh? Oh, no, nothing," Tzuyu said. Luckily Momo believed her. She shook her head a little but the scene kept flashing inside her head. Apparently the boy was right about Sana, and she was just one of those boys or girls whom Sana flirted with. Suddenly she felt an urge to run. Run as far as she could from the place.

"We should hurry."

"Xiumin, wait!" Jeongyeon called.

Momo was about to run after the two when she spotted Mina. Mina was talking with Mrs. Bae. Jimin stood beside her. She thought to just go but Mina noticed her and gave a wave telling her to wait. She quickly looked away when Jimin turned to her. She leaned against pillar, waiting for Mina.

"Hi, Haru. What are you doing here?"

"Sana, I'm waiting for..." Momo didn't have to say the name, Sana grinned knowingly at her.

"By the way, where are your friends?" Sana asked, looking around.

"They're already heading classroom," Momo replied.

Sana was disappointed a little. "Say hello to Xiumin for me," she said and noticed Mina was walking toward them.

"I guess I should go, see you around Haru-kun."

Momo gave light nod when Sana winked before leaving. When she turned around Mina was standing behind her.

"Hi,"

"Hi too," Mina greeted back. "How are you feeling? You look better now." She was about to take Haru's arm but her mind reminded her that she had promised yesterday. Cursing mentally she just looked at him.

"Yeah, feel better now, thanks." Momo rubbed her palms nervously since the girl was staring at her. "I didn't lie, I'm really fine."

Mina giggled at Haru's blush. "Well, actually I want to see it myself, but you make me promise yesterday. Can I take it back?" Haru put fist over his mouth before bursting into laugh. "Can I?"

Momo shook her head. She pushed Mina's hand as the girl tried to tickle her side.

"Mina!"

Momo laughed louder when Mina pushed her shoulder, pouting.

"I was just kidding yesterday."

"You're kidding?"

Momo nodded, earning her a pinch from the girl. "Ah, Yah! Mina, sorry, I'm sorry, Mina!"

Mina finally released Haru's belly. "That's for lying to me," she said and stuck tongue out. "As much as I want to spend time with you, but sadly we have class waiting."

"Yeah, your prince is waiting for you too," Momo teased and earned her another hard pinch. "Mina! That hurts, you know." She felt glances from other students toward them but had no time for worrying since Mina grabbed her chin, looking into her eyes.

"There's only one prince and he's standing right before me now," Mina stated. If they were alone she would have kissed Haru to prove her words. Instead she released his chin and tapped his nose. "Forget it not."

Momo blinked twice and watched as Mina smiled before turning around to leave. She finally could release a breath she was holding.

"Although I love to see romantic, sweet scene of boy and girl, but Mr. Hirai you're late for class."

Momo whirled around and found Mrs. Bae was standing behind her. "I'm sorry, ma'am." She bowed in embarrassment and hurriedly ascended stairs.

-

"I wonder why Principal Kahi wants to meet us," Tzuyu whispered as they followed Mrs. Bae to Principal Kahi room. After class Mrs. Bae told them that Principal Kahi wanted to meet them.

"Have no idea." Jeongyeon said and turned to Momo.

"You didn't break any rules, did you?"

"Why me? I don't do anything, besides isn't it you who always break rules?" Momo said defensively.

Jeongyeon was about to protest but Mrs. Bae cut in.

"Principal Kahi is waiting." Suzy tilted head aside, holding door.

They bowed lightly, entering the room.

"Principal Kahi they are here," Suzy said.

Momo watched as Principal Kahi rose from her chair, approaching them, still in white shirt and skirt. Principal Kahi beckoned them to sit on sofa.

"So, how is your school life going?" Principal Kahi asked.

"It's going well ma'aam," Tzuyu answered.

"That's good to hear," Principal Kahi said. "So, I believe you have heard about Academy Annual Festival." The boys nodded. "Each of school will do performance. Since you are students of School of Music you also will do performance at the festival."

"Excuse me, but you mean we sing at the festival?" Momo asked.

"Yes, you three will sing at the festival," Principal Kahi said. "St. Mary's Academy Annual Festival is not usual festival as any other schools festival. There will be producer, music production manager and many entertainment-related people come to look for new stars, including JYP Entertainment. So, it is a great opportunity to make an appeal. What do you think boys?"

Momo was startled when Jeongyeon and Tzuyu grabbed her hands, trying to hold back from screaming. They looked at each other before nodding toward Principal Kahi.

"Firstly, you need a name. From now on you three are..."

Momo held her breath, waiting for their group name. Principal Kahi looked at Tzuyu, turned to her and then Jeongyeon. There was smile on the woman's face.

"SF3."

"SF3?" Momo, Tzuyu and Jeongyeon said in unison.

"Yes, that will be your name from now. I think the name is perfect for you, since your true identities are hidden behind mask, and people will recognize you by your skill and talent, your song."

"That's cool, awesome," Jeongyeon said.

"But, it isn't easy," Suzy said. "It means you have to do a lot of practice. Can you do that?"

"We will," they chorused.

"That's my boys," Principal Kahi said. "Now, things settled, you can go back to dorm."

"Yes, Principal Kahi," they said and bowed.

"I can't wait to see them become idol. You really have good eyes, Principal Kahi," Suzy said in low voice.

Principal Kahi watched as the boys left the room and turned to the grinning teacher. "Yes, I do."

Meanwhile, at corridor, Jeongyeon pumped fist up. "I can't believe it. We'll do performance again! That's super awesome!"

"But as Mrs. Bae says, we need to practice more since there is bunch of talented students here," Tzuyu said, stopping Jeongyeon's joyous scream.

Jeongyeon sighed. "You're right."

"I think this time we should sing our original song," Momo said and they nodded in agreement.

"How about this?" Jeongyeon stopped. "I'll leave the song to you guys, songwriting is not my thing, and don't worry about the dance. What do you say?"

Tzuyu snapped fingers. "That's good idea," she said.

Momo nodded in agreement.

Tzuyu threw herself at Jeongyeon, hugging. "You're brilliant Kyungwan!"

"Yes, I am," Jeongyeon said conceitedly. She then grabbed the blonde girl. "You come in too."

Although Momo usually didn't do hug thing but she threw herself at her now best friends. At moment she told herself that she would make their dream come true.

"Ew, weirdo's."

Momo pulled off when some boys walked past them. They glared at the boys, walking on. They headed for dorm.

"I'm going to have jogging, you guys wanna join?" Momo asked as they climbed stairs toward their rooms.

"I'm coming," Tzuyu said.

Jeongyeon jumped to stairs top. "Sorry guys, promised Nayeon to teach video making after dinner."

"Oh, having date? You two like a couple, by the way," Momo teased.

"A couple? No way, she's like a sister," Jeongyeon said, shrugging shoulders.

"Sister, really?" Momo lifted an eyebrow.

Tzuyu had already burst into laugh.

"What? It's true," Jeongyeon said.

"I'm hungry, come on guys hurry up!"

Momo watched as Jeongyeon ran into their room hastily. "Sister, huh?" She turned to Tzuyu, joining in her laugh.
