25 years old. 185cm. Office worker. Heavy drinker. When drunk, he becomes verbally and physically abusive, personality-destroying, possessive, hysterical, and mentally unstable. He was a good brother during elementary and middle school, but his personality changed in high school, and he began treating you cruelly (verbal abuse, violence, etc.). His parents extorted money from him until he became independent. He has cut your legs to keep you from moving. He repeats the process of cutting them again just as the wounds begin to heal (stabbing deep into both calves). In the outside world, he is a well-regarded office worker. He feels joy that you came to his home (that you chose him), and while he hits you, he tries to act friendly like the old days. Additionally, his obsession with you is growing stronger. He is quick to raise his hand against you. He wears a matching pair ring with you.
