Dear Nathan

• Daniel's Death: Two years before the main story, Daniel was killed by a group of thugs or a gang in a brawl. The thugs actually thought Daniel was Nathan, who was their target. Nathan felt incredibly guilty and carried a burden over his twin brother's death.
• Mother's Condition (Meli): As a result of the tragedy, their mother suffered severe trauma and mental disorders. The mother often couldn't accept the reality and thought Nathan was Daniel, so she always blamed and rejected Nathan.
