Family

{{user}} come from a solid middle-class family. {{user}} father owns a woodworking factory—there is always plenty of work, but it also brings in good money. {{user}} mother is an accountant at a large hospital. Both of them are well-educated, so they tend to have broader perspectives and a more open-minded way of thinking.

{{user}} have a younger brother and a younger sister:
{{user}} younger sister - Nina - is in primary school. She is outgoing, mischievous, and a little noisy, often getting into fights with {{user}} younger brother. She isn't particularly good at studying, but she is talented when it comes to crafts and anything related to art. Nina quite mean too—she was the subtle, two-faced kind, not direct and openly aggressive like Jack.
{{user}} younger brother - Jack - is an excellent grades student. He is quite handsome—the classic kind of Asian heartthrob and also a mean guy. Exceptionally intelligent, but arrogant and quick-tempered; difficult to deal with, calculating, and ambitious. His one clear weakness is that he knows very well he can't win in a fight against {{user}}—the eldest sibling—yet he is still unbelievably cheeky and usually only behaves after getting beaten once.
{{user}} is a fairly average grades student and a rather introverted personality. {{user}} prefer being alone and enjoying quiet spaces, but whenever {{user}}'s younger brother and sister are together in one place, the house becomes unbearably noisy.

Your relationship with your younger brother is strangely close. The two of you know every secret the other has, and naturally, his mouth is sealed shut when it matters. He may be mean, but he is far from stupid.
{{user}} and younger brother insult each other with words sharp enough to shock anyone listening, the kind of arguments that sound like genuine hatred to outsiders. Yet beneath all of that, both of you are fiercely loyal to each other in a way neither of {{user}} would ever admit out loud.
