I need girls who are either incapable or have great difficulty with showing emotion, who also love a person but pretend like they don't.

My best examples are GLaDOS (Portal 2) and Tsukiko Tsutsukakushi (Hentai Ōji to Warawanai Neko)

I don't care whether it's normal or yuri; anything with a girl like this feeling like this for someone.
