The story was weird

basically a guy and girl age around 18-20 years old

I think somehow the guy got weird abilities that make them "presence "invisible to others but not to other people

Like example : the guy turn invisible and only the girl can't see him, there's a scene where the girl was taking bath, wearing clothes, studying and the girl can't feel the guy presence at all. The guy de-actived his weird power and ask the girl you really did'nt notice me ? the girl say she was'nt

the guy kinda gloomy type and the girl was also cold gloomy type

btw the power only works on the girl, all people can see the guy.

Similar to Seishun Buta Yarou wa Bunny Girl Senpai no Yume o Minai (but this manga have many supernatural abilities and the heroine have weird power to make her invisible unnoticed).
