i am not sure but i think its becoz solo promised gun that he will take responsibility of the other team member…
I think it's because solo left the team because Su Cheng was pregnant with his baby and he decided to take care of his baby so he couldn't handle his team and his baby at the same time. So I guess solo did kind of betray Gun...
I'm on episode 2.. I just don't get why shang yan and solo had a fight.. what did solo do?
I don't want to spoil too much but basically solo left the team right when they could have gotten the World Cup (you will find out why later). From then on, Han Shang Yan kind of hated him...
