The title means "Masquerade." Don't be fooled by how pure and literary it sounds. The story is mostly lighthearted, with a little comedy, everyday antics, and snarky commentary~
The male lead is Kyougou, Shinya Kogami.
Kogami won't be too out of character. I've only slightly exaggerated the gentleness and thoughtfulness in his personality.
The female lead is an original character, so don't worry about her being a Mary Sue~
A good start, why not update it?
