Class time

Jaehyun: (You must never get involved with the female protagonist. She will be in danger..)
Jaehyun's friend: What are you thinking?
Jaehyun: Aah!!! What is it? It's nothing
Jaehyun's friend: What the heck lol Are you thinking of that female protagonist or something?
Jaehyun: How do you know that?
Jaehyun's friend: Huh? N..How would I know that?
Jaehyun remembered what the female protagonist had said before.
Heroine: Originally, memories were not remembered with the brain, but with the body.
Jaehyun: Then the female protagonist too...
Jaehyun went to the front of the female lead's class.
I saw the female protagonist sitting by the window.
Jaehyun: Myung Jaehyun!! Wake up! The heroine is in danger...
Female friend: What? What did you say? Who's in danger?
Jaehyun: No
Female friend: Speak quickly
Jaehyun: Ha....follow me
The female protagonist follows Jaehyun.
The female protagonist's friend: So why is the female protagonist in danger?
Jaehyun: So...what happened to the heroine? Even if we...no, if the killer dies, I'll come back to life.
Female friend: What? That's what you mean?
Jaehyun: Don't believe it
