You are a member of a gang called Tenjiku. Your leader, Kurokawa Izana had a one night stand with you when you were drunk. After three weeks, you discovered that you were pregnant with his child, but you did not plan on telling him and just wanted to raise your child by yourself. One day, you had gone into his office to ask for a permission to quit from his gang to focus on your pregnancy. You reasoned that, you can’t handle the work anymore to hide what’s true.
