Nathan and Oliver were watching the whole scene of what happened between Aurora and that bicycle rider in the playground from the corridor right in front of their classroom while hanging out together.
When Aurora was about to get hit by that bicycle Nathan's heart was beating out fast in worries for her safety out of the blue like it was about to jump out of his chest and would run to save Aurora. He couldn't understand the reason behind his heart being so unreasonable to almost feel choked or being suffocated to see Aurora in danger and also the reason why his heart was at a relief to see her being safe and sound where Aurora was a complete stranger for him who he met a week ago. No matter how hard he tried to find the reason behind that sudden attachment his heart was feeling for Aurora, he could never come up with a solid reason. And also the sudden tensed and pressurized atmosphere that was developed after Aurora's seen that bicycle rider's face was attracting the curiosity of Nathan because it was his first time in that whole week to see such an expression on her face that contained so many emotional downfalls.
To know about that weird situation and to clear his curiosity he asked Oliver casually, "Who is that guy???"
Oliver took a look at Nathan motionlessly but totally ignored his question without giving any reply to him by turning back to observe the bicycle rider in the playground who was still watching Aurora who was leaving the place from behind.
Oliver's eyes were full with a strange kind of irritation and his face had a hideous serious expression. It was the first time for Nathan to see such a cold expression on Oliver's face who was a funny guy that usually used to play around happily like a tension-free kitten all the time without any worries or hate towards others.
Nathan's curiosity to know about that stranger and his connection with Aurora grew more after seen Oliver's strange behaviour as that stranger could make two people who used to laugh happily all the time at a loss of emotions with just a face-off.
But Nathan chose not to question about him from Oliver for the second time as he thought Oliver's silent or the ignorance of his question was somewhat mean to be his not knowing any details about that mysterious guy in the playground incident.
After a few minutes of silent Oliver finally exclaimed amusingly by breaking the ice while chuckling, "Who else could it be!!!"
But still, Oliver's eyes were fixed on that bicycle rider as if they were glued with that strange rider's presence and he was observing him carefully.
"Do you know him???", questioned Nathan curiously while looking at Oliver.
"Of course, I do.", said Oliver with a smirk but his gaze was still fixed on that rider even after Aurora's leaving from there.
"Then who is he??? Why don't you say me???", questioned Nathan with a serious expression without hesitating for a second as he didn't want to miss that opportunity to know about that stranger involved in upsetting Aurora along with Oliver at the same time.
"The devil… He is the devil that one should stay away from.", said Oliver in a serious voice while making eye contact with Nathan and at first hearing his words Nathan thought that Oliver was trying to scare or fool him by saying those weird things but the moment he took a look at Oliver, he could see that his eyes were full of indescribable disgust or hatred and he had no expression on his face while saying those words which was indicating that he was not cracking any joke or trying to be funny.
So, Nathan asked confusedly as Oliver's words were so misleading and were also raising so many questions in his mind, "The devil??? Mean???"
"You are still new. So, you know nothing but you will get to know soon once you meet him.", said Oliver while turning away from Nathan and his words were hinting that he was not open to share or interested in telling any details about that strange rider.
