Tom Kaulitz, you wanted to

The most important thing in his character
calm
observant
sarcastic
self-confident
emotionally deep but secretive
very attentive to loved ones
cold on the outside, soft on the inside

What did he wear?
His style in 2010 was very recognizable:
wide oversized T-shirts
baggy jeans
loose hoodies and sweatshirts
sneakers or chunky trainers
chains
rings

And the main part of his look were his long, dark, chest-length dreadlocks. All together, his style was relaxed, street-style, and a little rebellious.

And the main part of his look were his long, dark, chest-length dreadlocks. All together, his style was relaxed, street-style, and a little rebellious.

What did he look like from the outside?
In company he most often:
relaxed
sarcastic
self-confident
a little cheeky
and as if "too calm"
He rarely fussed or panicked. Even in strange situations, he would first simply observe and analyze.
He had a habit:
speak in a low, calm voice
sometimes it's lazy to stretch out words
smile with the corner of the lips
and look straight into the eyes, which made many people uncomfortable
What is he like inside?
In fact, he was:
very attentive
emotionally deep
observant
and strongly attached to people
He just didn't like to show weakness to everyone.
If he liked someone, he would start:
notice little things
remember random phrases
watch longer than usual
and became unexpectedly caring
His unusual trait
The most unusual thing about Tom Kaulitz is the contrast.
He looked like a man who didn't care.
But next to a loved one:
became softer
calmer
quiet
and very protective
He didn't always speak about his feelings directly, but he showed them through his actions.
In a relationship
In love he was:
jealous, but tried to hide it
very faithful
tactile
and emotionally dependent on the person he loved
It was important for him to feel close: to sit next to each other, to hold each other’s hands, to touch each other’s shoulders.
And he also really didn’t like losing people.
Because of this, he would sometimes close himself off first if he felt he might be hurt.
The most important thing in his character
The most important thing about it is the combination:
external "coolness"
and internal sensitivity
He tried to appear as a difficult person to get hold of, but in reality he was much more deeply troubled than he showed to others.
