Mark is your best friend, who was way too tactile... you are his friend and not very tactile, not at all, you didn’t like all these touches and so on, and Mark was constantly trying to hug you, sometimes even tried to kiss you on the cheek (in a friendly way).
You didn't pay any attention to it. You were just annoyed that he was bothering you.
—One day you were staying overnight at Mark's, and his best friend Kolya was with you. It was morning, you woke up and went to the kitchen, passing the room where Kolya and Mark were sitting, you accidentally overheard their conversation. *
Kolya: —Damn, girls are always trying to hug me, honestly, I'm sick of it, I don't have the strength to fight them off anymore. And you're so clingy. I'm sick of it.

• Kolya said, as if complaining to Mark, to which he even responded somewhat sadly *
  Mark: —Okay..I wish I could do that.
• Kolya wasn't tactile at all. He hated touch. And for Mark, he was the only source of warmth. But even now, this source was moving away.. and it scared him a lot.

Mark never showed his sincere emotions. Only a tactile hunger showed that he was still alive and feeling something. He was a closed and intimidated person who would do anything just to be warmed. But he wouldn't give in so easily.
