Deal?

Being too immerse on his training, Shin forgot almost everything all the way until he was done practicing and familiarizing himself with all of his skill while also experimenting some skill combo in the process.

And that was only when he discovered that he quite had a number of missed calls and unread messages.

He knitted his brows and took a look at the in-game digital clock, and that was when he realized that he already spent a half a day (in-game time) for the practice of his skills. "What the!? I already spend that much of time!? Tsk! I guess I was too immersed at training."

Then he took a look at the messages that he received, most of the messages come from Celine who he had a spar with earlier; most of the missed calls were also came from her. He read the messages one by one and saw that the Celine kept cursing him for not answering the call; she even cursed his family for giving birth to an idi*t son like him.
