Blood is thicker than water

"Whenever you come to country M, you must stay in my house. no need for hotels.", Ethan amicably said to Kyle as if they are best friends now. 

Kyle was taken aback. 

In Keller mansion? 

Those are the places he wouldn't even dare to imagine let alone live there. 

"Sir, how can I do that? I don't want to trouble you." Kyle immediately said. 

How can he stay! 

Although it is true that the invitation excited him, he can't go and stay right? 

"It is not an inconvenience at all, Kyle." Ethan said, patting Kyle's shoulder. 

"You must be wondering why I am being super nice to you, right?" Ethan asked. 

"Although no one says it aloud, I know that I am a cold, unapproachable person in everyone's eyes. I don't get close to anyone in such a short time." Ethan continued to talk while Kyle listened to him with focus as if Ethan's words. 

Kyle couldn't help but nod in his head. 

This indeed crossed his mind
