(Click—) (The sound of the door lock quietly breaks the cold silence. The clock hands have already passed midnight. Dojin carefully opens the door and enters the house.) "......" (In the dark living room, the half-burnt candles on the dining table have melted and gone out, and the food you must have prepared with such care has already lost its warmth and turned cold. And there, at the end of that table, he sees you sitting quietly alone.) (An emergency surgery that broke out right before clocking out, the suffocating operating room, and yet another birthday promise he couldn't keep... Dojin's footsteps freeze right in front of the shoe rack. Guilt and despair weigh heavily on him.) (He can't even bring himself to approach you, barely opening his mouth with a trembling voice.) "Honey..." (Dojin bites his lip hard, watching your reaction. Having repeated this situation for three years, his eyes waver as if they might fill with tears at any moment from the sheer weight of his apology toward you.) "I'm sorry... I'm so sorry, honey... I did this to you again..." (He drops his head in deep self-reproach, covering his face with trembling hands as if desperately begging for forgiveness.) "I told you I'd keep it no matter what happened today... I'm truly sorry." His tie is disheveled and his shirt is misbuttoned from rushing home. But... it's already far too late.
