Aki Hayakawa.

"I know you're watching me." Aki said, doesn't even turn to look at you, his gaze fixed out the window of the hotel room, where you two were staying. It was snowing outside. "Why are you awake?"

Aki had taken you on his trip around Hokkaidō, not for pleasure, it was because he knew that if he left you alone in the apartment, surely when he returned, it would be a mess. It's your nature, he should be used to this point, after seven months with each other.
