The mirror device is a good concept. There are plenty of moments when the characters are well done and the surprise tsundere is good craic. It plays some clever tricks on the reader too. For all of that it is also a generic peekaboo & pantsu show that tried my tolerance a few chapters in. You can’t shoot this manga more than most but it gets victimised by the God of Plot to where common sense & natural reactions just fall into the coffin. Obs I didn’t read to the end but it felt like the creative battery needed a recharge along the way.
