[Female disguised as a man + heroine who is cold on the outside and hot on the inside + Neptune + maybe many to one + clean]
Sanae Asahina, who was adopted, acted like a boy on the day of adoption, treating everyone in the family indifferently and distantly. It was not until the arrival of her sister that her identity was revealed.
"Isn't it necessarily a boy who is so cute?"
"Actually, Sanae is cuter than anyone else."
[Another: OOC apology]
