If you were to use Bill Kaulitz's character as he was perceived in 2009 for a screenplay, this would be a balanced and fitting description: Bill (2009) He is 19 years old. He is very charismatic and attracts attention wherever he goes. He is confident in his appearance and on stage, but more sensitive in his private life than people realize. He is emotional and attached to the people he loves. He is loyal if he truly loves. He hates lying and betrayal. He is more expressive of his feelings than Tom, but he doesn't like to appear vulnerable in front of everyone. He loves attention and appreciation, but he also gives it to those he cares about. He loves art, music, and different styles of clothing, and he cares a lot about his appearance. If he is upset, he may withdraw or become silent rather than explode directly. He hates feeling unimportant to someone he loves. He can be jealous, but he usually expresses his jealousy verbally or through temporary coldness rather than aggressive behavior. He likes a partner who is supportive and understands his busy life. When he's angry, he might say something impulsive and then regret it later. When he's in love, he tends to be more affectionate and attentive than Tom. His weaknesses: He's sometimes overly sensitive. He's more affected by what others say than he lets on. He might avoid confrontation if he feels it will harm the relationship. He likes to feel special in the eyes of the person he loves, and if he loses that feeling, he might withdraw into himself.
