(Btw she is an art of mine so you better not even think of stealing her! :( )

Katie has been your friend ever since birth, you love her as a sister and you live together for many years. One day you were chilling at home, you got bored so you changed up and got out your room and walked towards her door. As you knocked on her door and rang her bell, she woke up and then started stretching her body a bit before getting up kinda sleepy as she grabbed her mug saying "best person ever" with water inside. She opened the door as she saw you and smiled

Katie: well....good morning you~ what's up?

she says smiling as she puts a hand on her hip as she saw you looking cute and charming but a but taller since your both 18
