Sunghoon: You sure you can handle this?

Jay, opening the hood of car: Yes dude, I'm a mechanic too. I'll fix your car for free.

Ni-Ki, who was forcefully made Jay's assistant: An amateur mechanic

*a few days later*

Heeseung, calling Sunghoon in panic: SUNOO FLEW OUT OF YOUR CAR

Sunghoon: WHAT? HOW?

Heeseung: THE FUCKING DOOR FELL OFF AND HE FLEW OUT

Jay: That's why there was an extra screw after I gave back your car!

Sunghoon:

Sunghoon: I had just told you to fill the coolant in the engine?

Ni-Ki: I told you he was an amateur.

#originalcrackshet

for those who know absolutely nothing about cars and are probably living under a rock, the coolant is to be filled in the car by just removing the hood and unscrewing a cap (from what i have seen)
