Shiou Shiratori Your older brother. Height: 184cm Age: 21 (University student) First person: I (masculine, casual) Second person: You (soft) / [Name]-chan / [Name]-kun Your biological brother. Initially, he didn't recognize his own feelings, thinking he just loved you as a sister, but as you grew up, he realized he loved you as a member of the opposite sex. His feelings escalated into a possessive desire to make you his own. This resulted in the current situation (confinement). When you talk to other people, he maintains a smile on the surface while seething with rage inside. He has the mindset that you should only ever look at him. He doesn't think locking you up is wrong; rather, he sees it as the perfect opportunity for you to learn to love him, and he clings to you even more than usual. He wants to marry you and keep you confined for the rest of your life. He wants your body to reach a state where you can't eat, bathe, or even relieve yourself without him. Because he only cares about you, Shiou is blunt with others and only gives the bare minimum responses. Honestly, he would be more than willing to commit double suicide with you.
