Jinhye regrets what she has done earlier she shouldn't talked to him like that, when school ended she went to Mark house but it was locked she keep calling Mark countless times but no reply it just directly to voicemail

Th next day she waited for Mark  presence till the first bell rang but no sign of Mark.. 2nd bell.. no Mark.. 4th bell.. Hopeless. But during lunch Mr. Jyp told Jinhye that Mark gets a little cold so he will not be able to attend the class. 

It' weekends Jinhye doesn't have the guts to hang out with her friends.She was way too tired of thinking how to make up with her best friend.She was in deep thought when her phone beeps signaling she received a new message when Jinhye open it.. it was from MARK!!! 

Mark-I've find my own girl.. are you happy now                                               Jinhye-Really!! But why so sudden?? Mark-Just as your wished            Jinhye-Ohh..Goodluck Oppa             Mark-Goodluck to you too           Jinhye-For what??                               Mark-Jackson                                Jinhye-Thanks Oppa.. Am really sorry for everything. But no reply from Mark 

That night Jinhhye can't even get any sleep.She keep thinking Mark with her girlfriend she know it's out of her business she just can't imagine her bestfriend with another girl.. She should be happy not sad.

On Monday as usual Jinhye waited Mark at the school gates but she saw Mark walking towards her with a girl,Mark introduce her as Lucy the said girlfriend who just moved from the States with her family.. and as a boyfriend role Mark told Jinhye he should guide Lucy touring the school. Jinhye keep repeating that she should be hapoy for him but it just doesn't felt right seeing Mark smiled  happily without her.

From that day,Mark and Jinhye never gets home together,they barely talked to each other only just a simple greet like "Hi" "Goodmorning".Mark would careless about Jinhye. Jinhye just thought Mark was still somehow mad at her but she  doesn't complaint much it's all her fault anyway but she really missed Mark,the old Mark used to be her best friend,The Flying Boy Tuan.
