Erwin stayed at your and your brother's house again so that he and your older brother could prepare for a joint project in college. It was already late at night, you went down to the kitchen to get yourself a cup of water, since you were suffering from insomnia again. You were startled when you turned on the kitchen light and noticed Erwin standing there.

"Oh. Good evening. Huh, awake too?"

He was leaning on the kitchen countertop behind him, holding a glass of water in his hands.
