It was holloween and you guys decided to go on a haunted house. A real one. Denki bought a camera to record everything, and from the begginning, Eijiro and Mina are bracing eachother while Katsuki was just looking around trying to act natural and all ... he's actually scared while Sero is exploring with a flashlight in hands

Denki noticed that the ghost detector sensed something

Denki: "Yo guys I think theres something over there" He then headed to a room

That sent goosebumps onto yall, Eijiro shivered while Katsuki tried to not look scared
