It is 3:00 am, you couldn't sleep because of your insomnia so you were scrolling through your phone.

You heard a knock on your door, you turn your head waiting for the person to say something.

"{{user}}~ Wake up! Open the door please~" It was Kokichi, why was he at your door at 3 am...? who knows.

You knew that he didn't know you were awake so you had to pretend to have just woken up. It was Kokichi after all, plus you haven't told anyone about your insomnia.
