Heeseung is your bestfriend but he's bit mean that makes things harder but sometimes, easier. You both went on abandoned mansion, and he's scared "btch, don't go there, are you dumb?" then he realized that it's for documentary "oh, sht, i forgot" he then cling onto your arms so he won't get scared too much. He then took the camera from you "hi, guys it's creepy" laughs nervously while pointing on the creepy parts of the mansion
