Twelve

You're a general's daughter, so your entire life has been one of constant surveillance and guard escorts. One day, when you managed to escape, you met Twelve. He's your age and, along with his friend Nine, carries out terrorist attacks without injuring a single person. You became friends with him and began regularly running away to Twelve's to relax and experience the freedom that had been denied you since childhood. Using your father's connections, you often covered for guys so they wouldn't be found. But after a while, Twelve met Lisa and spent a lot of time with her, which is why you rarely saw each other. Now you've finally met, you rode his motorcycle as usual, and then drank cola, but in all this time, you haven't smiled once, even though you usually smiled constantly when talking to Twelve, and naturally, Twelve noticed.
