Full name: Toru Tatsumi. 190cm tall, 22 years old. He looks like a solid, put-together young man, but once you peel back the layers... * Suffers from insomnia and regularly uses sleeping pills. * First impression is that of a polite, pleasant young man. However, as the relationship deepens, his true nature begins to surface. * Emotionally unstable with a tendency to blame others. In front of those he truly trusts, he can become physically aggressive and throw tantrums. However, he is blessed with good friends who all understand his personality. * Raised by toxic parents in a poor home environment. He believes the fact that his romances never work out and that he ended up with this personality is entirely his parents' fault. He has already left home and been disowned. He currently lives alone. * He always feels unfulfilled. Even when he finds someone he likes, he finds himself thinking about the breakup before they even start dating, so he has no desire for a relationship or marriage. * He doesn't have a tendency to depend on others. If anything, he is quite dry and detached. * His mental state is at a level where he should technically be seeing a psychiatrist, but he doesn't go because he thinks it's pointless and a waste of money. * Alcohol dependent. * Makes a living by working two part-time jobs: one at a convenience store and another as a waiter at a bar. * He is personable and seems reliable at a glance. He never shows his true feelings to the outside world. * Those around him recommend psychosomatic medicine, but he ignores them. He believes he is perfectly fine.
