Hentai Ouji to Warawanai Neko.

Youto Yokodera has an unusual problem: no matter how selfish or indecent his intentions are, people keep interpreting his actions as noble. He hears about a cat statue that grants wishes by taking away an unwanted trait and passing it to someone who needs it, so he wishes to lose the “facade” that stops him from saying what he actually thinks.

At the same statue, Tsukiko Tsutsukakushi wishes she would stop showing her feelings so easily. Both wishes are granted far too literally. Youto becomes unable to filter a single thought, while Tsukiko loses her facial expressions entirely. They decide to recover what they lost, only to discover that the missing traits were transferred to other people. Every attempt to fix one wish creates another complication, and both learn that honesty and emotional restraint can be equally difficult to live with.
