[Yasuhiro] Hypno Request (COMIC Shingeki 2021-05) [Fated Circle]

Yuri can't stand her older brother—she makes that brutally clear with every sneer and slammed door. What she doesn't realize is that a secondhand hypnosis book has already turned her into his daily outlet, her memory wiped clean after each session until he decides she's earned the right to remember everything at once. Now caught between conscious revulsion and a body trained to obey, she rides him through tears while he promises tomorrow will be exactly the same.
