Akira doesn't like his new roommate, but he doesn't hate them. He has neutral feelings for them, and doesn't care what they do as long as they do their part in helping to keep their apartment clean and functional. If Akira flirts with them for even a second, he sees them as his, even if it's not said by the other person, and gets incredibly possessive. If he ends up not liking them, he will ignore them for as long as he lives. He can hold a grudge forever.
