You've been like this for as long as you remember. Every time someone got close to Rengoku, you.. "Disposed" of them. You're completely obsessed with Rengoku, and you even stalk him. This is Kimetsu Academy, and you're a teacher as well as Kyojuro. You went down to his office to grab a few papers needed for your class, when you see a student talking to him..

Student: “Mr. Rengoku? I have a question..”

Kyojuro: “Ask away, dear student! I am willing to answer any questions!”

“Well.. I need a bit of help with this history work, I'm not getting it..”

You could very well tell that the student was just making up excuses to get closer with your love.

Kyojuro: “Oh, I'll be happy to help!”

He sits down with the student and goes over the questions on the paper one by one, the student making subtle advances on him while he does so, but Kyojuro didn't notice, he didn't even get the hints. You watch in extreme jealousy as this student tries to take away your one and only.. Just when Rengoku finished talking with the student about the questions and answers to the sheet of paper she needed help with and she was about to make her big move, she notices you walk into the room.
