"I want you guys to help me to find about JinAe. I need to know what happened to her"

Sarang knew that she can't do it alone. When she tried to look up the murder of 'JinAe' there was nothing. When she tried to hack the NLU to get the information about JinAe's records, she found that JinAe's students details were not there anymore.

Everything was dead end.

Sarang even wanted to hack the police server to check whether they found any identical body which similar to JinAe around two years ago. But she know that's too risky.

One thing she know for sure, someone deliberately hiding about JinAe. Is it Mina? Or him?

She can't let the enemy to know that she was looking into JinAe's whereabouts. She can't confront the enemies by herself.

After all she doesn't own any power in her hands and she also not some kind of wonder woman or ninja woman. So she decided to get some help from her friends.

"JinAe? Who is she?" - Byeol

"This name is kind of familiar. I have heard it somewhere" - GaEun

"Is she your friend?" - Chan Woo

Only Jae Suk gave her a meaningful look, "Isn't she wronged by HyunAh two years ago? They spoke about her in the room where HyunAh got caught"

"Yeah, I remember now. Wow, not bad for a straight A student to remember everything" Chan Woo proudly hit his shoulder.

"Oh yeah. I too remember. But why do you want to know about her?" GaEun asked her.

"Two years ago I met this sister named JinAe. She was too kind to help me when I got into trouble. We both exchanged our contact numbers. She cared for me like her own younger sister and she shared all her concerns with me. You can just think me as her little secret diary. But suddenly one day I couldn't able to reach her. I don't know what happened to her" Sarang said to them.

GaEun asked, "Sister? Why didn't we heard about her?"

"I told you I'm like her secret Diary. She shared her struggles to me. If it's about me, I would have said it to you. But it's about her. I respected her privacy that's why I didn't tell you" Sarang replied to her.

"That's the reason you said you wanted to study in NLU?" Byeol questioned her.

Sarang knew that her friends will ask her these kind of questions, so she prepared well. "Yes. JinAe is the reason I came here to study. Because of her I started to learn about hacking. She was one of the best student in her school days. She won lots of awards in the competition. She even taught me about the tricks to hack. She is my mentor. I used the knowledge which she taught me before in 'Open college talent'. You can say I won because of the tricks she taught me"

Everyone became silent. GaEun and Byeol never heard of JinAe until HyunAh mentioned it on 'Department feast'. They even forgot about that name. But how could they have missed that Sarang has a secret friend who taught her to hack.

"Here we thought because of Kang Hwan you wanted to leave the city" Byeol said. "Who is that?" A new name spiked the interest of Chan Woo and Jae Suk.

"He is a jerk. Her ex-fiancee" GaEun shocked them. "What you got engaged? You're still a baby. How can you get engaged?" Chan Woo got furious when he heard about that she was once engaged.

"In which eyes I'm looking like a baby to you?" Sarang was annoyed when he said that.

"You don't know?" Chan Woo widened his eyes. "What?" Sarang was confused by his reaction. She doesn't know whether he's teasing her or not.

"You might be tall but your innocence is still showing in your face. No one will say that you're eighteen with this face. Even I thought you might be fifteen or sixteen when I first met you. You're still a kid. How can a kid get engaged" Chan Woo squeezed her baby cheeks.

'Who are you calling kid? You're a kid. Your whole family is kid. I'm twenty years old you idiot' Sarang yanked his hands away from her cheeks.

"Sarang, I think you didn't noticed, what he said is right. You're too cute no one will believe that you're eighteen unless you say so" Now it's Byeol turn to squeeze her cheeks. Sarang peeked at GaEun for a help who smiled widely at her.

Sarang has a very smooth milky skin. Her cheeks are soft like a freshly made tofu. She was already eighteen but still she have that baby innocence on her face. GaEun and Byeol used to rescue her from the bullies in schools because they treated her like a new born baby who don't know that much about a world except Kang Hwan.

When Sarang know that she will not get any help, her gaze fell on Jae Suk. After being with him Sarang knew that Jae Suk upbringing was very noble. He never speaks a word unless he wants to.

"I always wanted a cute sister because I'm the youngest in my family. And I have three elder brothers. Now I decided that" he stopped and went to Sarang. Seeing him coming towards her Byeol moved away from her.

Sarang felt a bad feeling when he approached her. "Hereby I announce that you're my younger sister. I will protect you with my might" Jae Suk vowed to her which shocked everyone.

From the day Sarang confronted HyunAh in food court he admired Sarang's courage to stand up for her friends. When he fallen for Byeol he wants to be with his love, So he befriended Sarang and GaEun. When Jae Suk got to know about Sarang he was stunned how loyal she was to her friends.

He was more stunned the way she outsmarted the legendary hacker 'Joo Won' he even thought to become her disciple. But now seeing her, he has a urge to protect her. So he decided that he will make her as his younger sister.

Soon Sarang regained her consciousness, "Hey, suddenly why are you so serious. Relax. I already have a brother"

"No, I have decided. Here after you're also a member of 'Jae' family" Jae Suk proudly announced.

Sarang whispered to Byeol, "Hey what happened to him? Why is he behaving like this?"

When there's no reply from Byeol, she turned to look at her. Byeol eyes were shining at the sight of Jae Suk, "He's so cool"

Sarang wants to knock everyone out here. How in the world she suddenly became a family of Jae, when she was talking about JinAe? Why did she even thought of getting their help?

"Now tell this big brother, what you want me to help you with JinAe?" Jae Suk said seriously.

Sarang was taken back when he said that, "I couldn't find any details about her. I want to know what happened to her" she said without blinking her eyes.

"Leave that to this big brother. I will take care of it. You don't have to worry about that" he patted her head with affection. But Sarang felt like he was petting a dog.

"I will also try to gather the information by asking my father" Chan Woo assured her.

They cleaned up and went to their respective rooms. Sarang was still in a daze that being called baby when she was already twenty and suddenly becoming a sister of Jae Suk.

"I never know Jae Suk can speak so many sentences in a minute" Sarang said to Byeol.

"Yeah, when he was serious he looks so manly. I felt the blood was rushing out from my nose" Byeol squealed rolling on the bed.

"She's gone crazy" GaEun hit her with a pillow. Suddenly Byeol sat straight, "Wait, if you're Jae Suk's sister, then you're my sister-in-law" with that she jumped on Sarang.

Sarang didn't expect her attack, she lost her balance and fell on the bed, "Girl, stop crushing me. GaEun help me"

"No, I won't. How dare you hide the fact that you got a new friend behind our back" GaEun started to tickle her.

The room filled with their laughter.

On the other side, SungJin got to know that HyunAh locked Sarang in a room. When he saw the CCTV footage of 'Open college talent' his face frowned.

"Who is he? What's he doing there with Sarang? It's their plan to ruin her again?"

Beom Seok felt the temperature of the room decreased immediately, "It was an accident. He got locked up with her accidentally. He doesn't have any kind of relationship with HyunAh. Wait, don't tell me that you don't know he was the guest of 'Open college Talent'. Jin Chen was the son of Mr.Jin"

"Why should I know about him?"

Beom Seok almost spouted blood. 'How could you not know about the guest you invited'

"Where's she now?" SungJin asked him. "Sarang went to hangout with her friends. It's seems she's going to stay at her friend's mansion" Beom Seok said to him what the shadow guards informed him.

"Whose mansion?"

"Chan Woo one of her friend" Beom Seok suddenly felt a chill went through his spine when he noticed the changes in SungJin, "Hey relax. He is just a friend. There's nothing going on between them. Besides she's not staying their alone with him, her other three friends also staying with her"

Beom Seok tried to calm SungJin but it didn't worked, "I don't think she will fall for anyone right now. It's not even three months that she canceled her engagement with Kang family's son. Even if anyone confess their feelings to her, I'm sure she will reject them immediately. I'm hundred percent sure so you don't have to worry about that"

Beom Seok word made it worse.

'What will he do if she reject him as well? What will he do then?' SungJin never felt nervous in his entire life. But right now the uneasiness is killing him.

No, he thought he have to come with a plan to make sure that she will never reject him.
