My baby's ? (p.js+ n.jm)

It was the weekend and jaemin was happy that he ended the week without breaking down. He was walking toward his locker to pick up his books while he was walking he was slammed into the locker he looked up to see his ex aka his bully changbin. He was scared because changbin would beat him up. He always do so he tried to run away but changbin gang gathered up and he didn't have a way to run. So they beat him up with no reason and left him on the ground. After a few minutes he get up and went to the bathroom to clean the wounds. After he finished he went home.
"Oh you're home" said jisung with a smile which turned into a frown soon. "What happened who did this to you?" Jisung said concern.
"Don't worry I'm fine" Jaemin said with a smile.
"Stop lying and tell me who did this I'm going to make them pay for hurting you" jisung said in a threatening way. Jaemin was scared so he told him everything and cried till he slept. 
In a call
"Bring Seo changbin here"
"Okay sir"
"And his little gang"
Jisung ended the call.
In the evening jaemin woke up and was in pain so he cried. Jisung heard some crying so he ran to the room for jaemin.
"What's wrong baby? Are you hurt? Do you want some medicine or do you want to go to the hospital?" Jisung said
"Just cuddle me I will be fine" Jaemin said with a smile.
"Okay but the kids are worried about you do you want to see them" jisung said.
"Aww my little baby of course I want them let them come and cuddle me too," Jaemin said excitedly.
Jisung went and called the kids that jaemin want them. They went running to him crushing him in a tight hug while they cried.
"Don't cry baby's I'm okay now" Jaemin said in a cute voice. Jisung smiled at them and went to lay down beside them. They cuddled all day.
When jaemin and the kids slept. Jisung went out.
"Where are they?" jisung said in a cold threatening voice.
"In the basement sir," one of the men said.
They went to the basement to see changbin and his gang.
"So who is changbin?" jisung said.
"I'm changbin and who are you why are you doing this" changbin said with confidence.
"You hurt my baby and you should pay for it," jisung said with a smirk.
"Oh you mean jaemin I guess don't you know what he did in the past?" changbin said with a big smirk.
"I don't care about the past and it's not your business so you shouldn't talk about my baby like that" jisung said with a growl. And punched changbin right in the stomach. Changbin hissed in pain.
"I will leave you to go but if I heard that you hurt my baby again I will kill you and you don't want to try me," jisung said.
"I will leave them to you," he said to the man who is with him. And left.
When jisung arrived home he saw jaemin in the living room walking around worried about him since it was so late.
"Jisungie where we're you I was worried about you," jaemin said crying I hugged him and assured him that I'm okay and I had a meeting to deal with.
