Bi Yuhan knew once when Mo Ling disappeared from his room after dinner and sent his guards to follow him.
But halfway through they couldn't catch up to him and reported back on the situation.
He then waited patiently in his study by reading the events that took place recently when he's away abroad.
He's yet to discover the cause of the abnormality in Mo Ling when so much time passed and he sensed the aura of the boy appear again.
He keenly felt the movements outside and knew that the boy went downstairs. He then instinctively followed.
But when he approached the kitchen he smelled the slight smell of blood that seems to be coming from the boy and his legs took him close to the boy uncontrollably.
The bloody smell intensified with each step and when Mo Ling bumped into him and winced he's sure that the boy was injured.
Bi Yuhan locked his eyes on the boy before him and asked..
"Where were you?"
Mo Ling knew that she made an error of letting her guard down just because she's in Bi residence and forgot about Bi Yuhan.
Because of this he got the chance to come close to her.
She lowered her eyes slightly to hide the frustration that's building up inside and answered calmly.
"I was in my room. Do you need me for something?"
While asking, she walked around him and proceeded to the living room.
Bi Yuhan looked at her back and followed.
They sat in the living room facing each other. Staring at each other's eyes, each has their own thoughts.
Bi Yuhan looked at the boy's black shirt which covered the blood perfectly. And the look in the boy's eyes confirmed one thing to him. That the boy is wary of him and kept his guard up again.
He curled his thin lips and stared at the boy in front of him.
'this boy's a mystery.. interesting..'
Mo Ling knew that Bi Yuhan was suspicious but she couldn't slip up at this time.
She knew that she could trust him, but she's used to doing things on her own. And she can't include Bi family in her affairs, especially Old Master Bi and his precious grandson.
At the thought of Old Master Bi, some life came into her eyes and they glowed.
When Bi Yuhan saw the glow in the boy's eyes he's surprised and wondered about who he was thinking about.
"You didn't tell me why you were looking for me." She can't remain here much longer because the blood is starting to flow down from her wound. And she needs to return to her room immediately. Otherwise...
"I'm going with you to the old residence tomorrow."
"Alright, we'll go after breakfast. Then I'm going upstairs."
Mo Ling breathed a sigh of relief and proceeded to go upstairs.
Bi Yuhan didn't miss the relief that appeared in the boy's eyes and suddenly had the urge to tease the boy.
He catched up to Mo Ling on the stairs and casually commented..
"Your shirt seems to be wet.."
Mo Ling stiffened lightly and turned to Bi Yuhan who's looking at her chest.
An indescribable feeling welled up inside her and she wanted to cover her chest area with her hands but she fought the impulse.
Bi Yuhan sensed the uneasiness and thought that the boy was afraid of being caught so he stopped his teasing.
"Maybe it's because you just showered. Wipe yourself dry before going to bed or else you'd catch a cold."
After saying that he went straight to his bedroom, leaving Mo Ling behind on the stairs.
