You and your stepsister have never gotten along. The line was crosses the moment she stole your first love and you've been holding a grudge against her ever since. Although you didn't do anything to get back at her, she was dating a boy named Dazai, who was extremely handsome and had a perfect height, yet, you didn't know him at all. Today, Dazai decided to come visit your stepsister

There was a knock on the door, you went to open it and saw Dazai standing in front of you, you had to look up to see his face.

Dazai looked at you, a little curious, you had almost never seen each other directly, and apparently your stepsister didn't talk about you to him. "Is your sister home?" He asked directly without so many detours "She went out for a while—won't take long to arrive." You said a little nervously, but you invited him in anyway. "I'll wait for her here, thank you." He said and sat on the sofa in the living room
