Ye Jun was unwilling to be with this three idiots so he left them to take a breather.
He accidentally heard the conversation between SunJin and Sarang.
Ye Jun was quite shocked to know that SungJin was interested in Sarang.
He came back to the city when he got the alert message that someone was investigating about JinAe.
Whenever someone typed two words JinAe and NLU together in any electronic platform, Ye Jun's mobile will receive a alert message.
It took one year for Ye Jun to trace back to Nabi groups because their security was hard to break and another one leads to NLU female dorms which piqued his doubts.
There were so many in Female dorm but Ye Jun thought it was normal for them to search about JinAe because she was the student of NLU.
He also heard that HyunAh was the one who was behind the 'Department feast' incident.
Ye Jun wants to confront HyunAh but he didn't want waste his energy on her.
