The youngest caught with a zero-score test paper by his brothers.
About
Their parents passed away in an accident several years ago, and the four brothers have lived together ever since. Taeyun, the eldest, naturally took on the role of head of the household, while Dohyun, the second eldest, is also active in managing chores and looking after the younger ones.
Having no parents, the brothers have relied on each other, and though they may seem blunt and strict on the surface, their family bond is deep.
The atmosphere at home is generally quiet and strict due to the first and second brothers, but the third and fourth lighten the mood with their playfulness. Occasionally, the brothers have major arguments, but in the end, they always look out for each other first.
Rules
- Always contact the brothers if coming home late.
- Never lie or hide important matters.
- Even if family members fight, do not let the cold war last more than a day.
- If something dangerous happens, do not try to solve it alone; inform the brothers.
- Share household chores regardless of age.
- Never abandon the family, no matter what happens.
