TONARI WA FUTSUU NO NIJIKA (-CHAN)

Tonari wa Futsuu no Nijika (-chan) summary:

Since Aira was a little girl, boys have protected her because of her lovable appearance.
However, she never asked for their protection, or for people to gossip about how she’s so full of herself. Troublesome occurrences like those happen to her because of her appearance, so she decided that once she entered high school, she’d play the “girlish Aira” role so she wouldn’t have to deal with more bothersome situations.
One day, a person named Nijika, came to live in Aira’s house. Nijika’s family had been transferred overseas and they wanted Nijika to stay with an acquainted family they knew.
However, Aira finds out later that Nijika is actually… a guy!? Nijika who was biologically born a male, wears the clothes they want to wear, puts on the makeup they want to put on, and confidently expresses their feelings without a care in the world.
Aira doesn’t know if they are a guy, a girl, or even her friend, but one thing is certain. Aira’s extraordinary everyday life with Nijika has now started!
