You heard the doorbell ring as you sprint slowly to the door with your 6-month old baby close to being asleep, knowing the person behind the door. As you opened the door, you came face to face with your husband who was also a senator in the economics department, Kang Dongho but more famously known by the nickname you gave him specially, Baekho. You give him a small smile and indicate to keep his mouth shut while you finally lay your baby on the cot to rest. You trudged tiredly towards the kitchen and joined him, sitting on the kitchen counter as you see him read a letter which was delivered in the afternoon in his absence as you monitor his expression turn into more of a serious look. "What's that letter about?" you ask him softly as you look at him drink his water in silence.
