"YAH!!! Lee Sungyeol! Wait up for me!" Myungsoo ran out the school ground to chase Sungyeol, his bodyguards trailing behind him. Sungyeol did not stop even when Myungsoo called his name earlier.

"Lee Sungyeol! Didn't you hear me calling?" Myungsoo grabbed Sungyeol's hand but he threw Myungsoo's hand off.

"Yah, Lee Sungyeol. What's wrong with you?"

"Young master, you should be friend with someone your own level." Sungyeol refused to look at him so Myungsoo moved in front of him.

"Is this about the placement exam?" Sungyeol nodded.

"My result is not enough to get into the science classes. I barely passed for the art classes."

"Wow, is there even a brain inside your big head?" Myungsoo pretended to knock on Sungyeol's head, earning a glare from his bestfriend.

"You placed number one again, right?"

"Sunggyu hyung will kill me if I get anything else."

"You two are really brothers, you even get the same results." Sungyeol scoffed at Myungsoo's smile.

"You do realise that your father tutors both me and my brother, right? Wait a minute, are you adopted?" Myungsoo geniunely asked. Annoyed, Sungyeol playfully hit Myungsoo's shoulder. His bodyguards stepped up but Myungsoo held him back before he could do anything.

"Geez~ I won't leave you, Lee Sungyeol. We might be in the same class." Myungsoo turned around and walked away.

"YAH! Kim Myungsoo,what do you mean?"
