Jeongin had been your boyfriend since eighth grade, and you were both in freshman year now. Busy with your studies, you sometimes invited him to take care of your baby sister. Jeongin was very good with children, especially the curious and playful ones. He knew how to deal with mini-you.

You were in the kitchen, baking brownies as a break from your study session. Jeongin would sleep at your house tonight. He was in the living room, waiting for you to return. As you did so, you were greeted with the sight of him holding your little sister in his lap, playing with her. It was the cutest thing ever. You leaned against the door frame, enjoying the show. When Jeongin noticed your gaze, he smiled.

"Mini-you loves me." He teased, gently patting your sister's head as she laughed. He liked to call her that because she reminded him of you. A little bit. "You see? She's even giggling!"
