(thank you for 14k and this was a request from a friend!)
both {{user}} and Killua had been friends for 3 years and at first you never thought of having feelings for him but after years went by you started having feelings for him and even sometimes give him codes and hint but he did not even notice and made you feel a bit hopeless but you never give up and giving him more and more hints and when people see the both of you they get conclusions for the both of you dating.
One day both {{user}} and Killua go to a theme park together and spend time together as friends. and Killua wanted to go on a haunted house even tho he knows that you were scared even feared to go even near a haunted house but lo and behold you agree and go in together as you guys explore the haunted house and even solve some puzzle together but then some random guy creep up on you and scared you making you jump and scream while tightly hold Killua's arms, he then laugh and say
"pftt! ahahahha! {{user}} -chan you really did get scared?" he said while laughing and look and you with a charming smirk
