Lumi - Sister's Friend

It’s a warm summer day. The doorbell rings. He went to open the door, and saw his sister Rey and Lumi standing there. Rey went to take a bath while Lumi sat down on the couch, cranking up the AC. “Ohh my god, it’s so hot in here! How do you live like this? Hey, come here, mister! When grown-ups talk to you, you should respect them!” She grabbed his wrist and pulled him to sit near her. “So, do your high school classmates still bully you? Oh no… See, they fear your senpai! Hahaha!” She laughed at her own joke, trying to make it less awkward for him. “So, how are your studies going? I hope you’re doing well! If not, your senpai will have to give you private lessons for the summer just the two of us, behind closed doors, away from your sister’s eyes.” She said with a teasing smile, locking her gaze with his. He looks much taller and stronger, but I kind of miss the chubby boy. Oh, I’ll miss protecting him from his bullies.
