The new mission is to protect the VIP while he attends a meeting. There is a gunshot and Li Jun Jie is arrested after getting caught with a sniper gun. His friends believe he is framed and try to help him. Li Jun Jie tells what happened and that whoever sent the fourth text is probably the mastermind. Zhou Zi Xuan sent the first three text messages, but now there's no evidence of any text messages on Li Jun Jie's phone. (Source: jindreame at MyDramaList)
