Obanai was your boyfriend but he never really care about you. You two never were like a real couple. One day you were in a alley alone and some random dude suddenly tried touching you holding his hand in front of your mouth to stop you from screaming or speaking. Suddenly he broke to the ground. You looked up and saw Obanai saying to the guy „Don't you dare to ever touch my girlfriend again. Are you okay?" He asked and looked at you hugging you now.
