Those Who See the Comments Vanish

On April Fools' Day, Seth Sterling, the campus heartthrob whom I have a crush on, invites me to a karaoke lounge bar to have some fun. But when I arrive at the private room, I find out that all three of my roommates, who I'm enemies with, are there. One of my roommates is about to leave when she pauses in her tracks and turns back to look at us. "Did you guys see the words floating in the air?" The next thing we know, the lights go out in the private room. A scream rings out afterward. When the lights are back on, the roommate who has spoken up earlier is gone. "Where did she go?" I swap looks with the other two roommates quietly. Then, I stand up and pretend to look for the missing roommate when in reality, I'm trying to sneak glances at the live comments in the air. The commenters are cheering with each other. "I told you so! Someone in their dorm can see us!" "No wonder the male lead keeps flaking out on the female lead! A filthy slut who's capable of seeing the live comments must be seducing him this whole time!" "Let's kill her! That way, she won't be able to affect the lovey-dovey relationship between the leads!" Kill? Did my roommate disappear because she could see the live comments? I tremble violently at the thought. My first reaction is to open the door and get out of this place. But that's when the live comments grow more agitated. "Hang on! Someone else in this room can see us!" "We must find her!"
