So this chapter is JUST Soojin's scenes, they are in order and I will say when it happens in the MV as well as the lyrics that go over the scene

1)

The video opens up to Jake, Heeseung, Jungwon, and Soojin in school uniforms at a bus stop. They're happily talking and when the bus arrives they get up and start getting up. As Soojin gets up she looks around her. Like someone is following her. She narrows her eyes and look to the side. The camera changes to a view where we can see behind her. There's no one there but two shadows or werewolves. Soojin snaps out of it when Jake tugs on her sleeve. She gives him a strained smile before joining the three on the bus.

2) When the boys are standing with a birthday cake waiting for Jungwon

Soojin is standing on the right side. With Jake, Heeseung, and Sunoo

3) Instead of Jake's scene when he is pouring out the red drink

Lyrics: Honestly, I'm scared

My reflection in the mirror is unfamiliar

Soojin is stirring a red drink. It zooms into her eyes and flashes to Sunghoon's scene where everyone is cheering

4) Right after Sunghoon's dance scene

After Sunghoon's dance scene it zooms out of Soojin's eyes again and her eyes are blood red. It zooms back into her eyes and shows the scene of everyone sleeping in a room
