Xiao XiRans eyes were shining in amazement that he can't help saying those words. Although he heard about YuYan feeding her blood to Xiao YuRin, he did not expect the result. He only thought that YuYan was having a tantrum because she was forbidden to see Xiao YuRin, not until hearing his baby sister's explanation. 'Why can't RinRin drink my blood?! RinRin need my blood. He was getting well when he drinks my blood!' That was the words that YuYan kept on screaming whenever she had tantrums. It made Xiao XiRan confused, the question why would Xiao YuRin need to drink YuYan's blood made him tried asking about it but no one tried to explain. Xiao XiRan was eavesdropping on YuYan's bedroom door when he heard the reason why she was not allowed, but it was still not clear what's with YuYan's blood. Not until now that YuYan explained about what her blood can do for Xiao YuRin. Xiao XiRan thought for a second and nervously claimed. "But.. Mommy said you would die." His hear started beating fast. Beads of sweat began to form on his forehead while his back soaked in sweat after hearing what YuYan wanted to do. "No, I won't. So promise to help me or else RinRin will not wake up." YuYan persuaded with assurance. "It will be our secret. You will do it or I will kill myself!" She threatened. YuYan's threat made Xiao XiRan turned into a statue. He looked at his baby sister with a complicated expression. He opened his mouth, but there were no words that came out. Thinking about his brother's condition, accompanied by the possibility of dying, Xiao XiRan hesitated, but it didn't take too long when he finally nodded in response. YuYan decided to disregard her parents words. She no longer cares what will happen to her. All she thinks of was for Xiao YuRin to wake up. Their little mind started to work together. Thinking about how and when to sneak into Xiao YuRin's bedroom without being discovered. They both planned sneaking out at midnight. They were like a mouse trying to hide from the cat as they look around before running away. When they arrived in the kitchen, they opened the window and sneak out. Xiao XiRan thought that they can use the kitchen to look for something to eat as an excuse. Despite their flawless plan and cooperation, Xiao XiRan and YuYan didn't expect for Xiao YuYi to discover them on their first attempt.Xiao YuYi went to the kitchen because she felt hungry. When she saw her siblings, she was about to speak when Xiao XiRan opened the window and carried YuYan. Knowing how silly whenever they're together, Xiao YuYi can only guess. Xiao XiRan and YuYan are up to something and this is probably about Xiao YuRin."What are you doing? Big brother, why are pushing YanYan on the window?" Xiao YuYi asked that froze Xiao XiRan and YuYan who was about to climb up on the window.Xiao XiRan immediately put YuYan down, and in a swift move he jumped towards Xiao YuYi to grab their sister's arm and covered her mouth. "Don't tell mommy and daddy!" Xiao XiRan immediately exclaimed as he covers Xiao YuYi's mouth. He explained why they were trying to sneak into Xiao YuRin's bedroom. Xiao YuYi did not speak after Xiao XiRan let go of her. She remained sitting in front of them, looking back and fort to her silly siblings. Xiao XiRan and YuYan's heart was beating fast while waiting for Xiao YuYi to speak. They were both having a cold sweat while every second feels like forever. Xiao YuYi suddenly smiled sweetly and claimed. "Okay! I can pretend to be YanYan eating with big brother here in the kitchen while she goes out. But we need to wear the same pyjamas."
