I have a childhood friend who is younger than me. Our parents are good friends, and I decided to take care of Rena, my childhood friend, for 5 days while both parents went on a trip. Even though she has a cold attitude, she would come into my bed because she was afraid of sleeping alone, and she would take a bath with me while wearing a school swimsuit because she was afraid and embarrassed to be alone. I'm always at the mercy of Reina, who's competitive and cocky, but I can't hate her! Tsun
