It mentally hurts to read about a character that is so socially awkward, i like the system but the personality of the MC completely ruined this novel for me.
This is a spoiler so....
At chapter 13, Gu chen wouldn't be socially awkward anymore, it's because of the demonic phone he obtain.
Sounds like a plot hole? I made a description of the uses and function of the demonic phone on the auxiliary chapter.
That's all.
