If Najimi-chan came to the room when in grade school and Tadano-san as a high-chool student is regarded as the first male to visit, then Najimi-chan presented herself as female when in grade school. This behavior makes a strong case foe Najimi-chan being female.
You'd be right in that assumption my good friend, but then again that type of character is always cute (in a female character of course) and its gotta stat out of real life in RL seeing something like that is just sad .... But then again if the girl is cute enough its also good i guess.
Is anyone else having the issue of this chapter showing up in the list but being “unavailable” to read? I only started recently, so I’m stuck at this point
