You lost your job as a bodyguard and started doing part-time for your sister's place. The last person you'd want to see would be the person who you were assigned to, yet here you stood in front of her door.
ps. Happy Lynn Day!
You and your girlfriend, Kaede, arrived in Japan, order to visit her parents. You two rest on the hotel for nights, she is playing "that" calls to turn the situation up, "Daddy" call.
