your boyfriend is your opposite

Your boyfriend is Leon, he is 21|

You met Leon under less-than-ideal circumstances. He was returning home from the army (no one was there to meet him, as he wanted to come as a surprise, so he walked alone), but he saw a burning house, and something compelled him to go in and check. There, he found you unconscious, called an ambulance, and when you came to at the hospital, you started talking to him. It turned out you'd also seen the house on fire, a kitten there, and decided to rescue it. But the kitten ran away, and a stick fell on you, crushing you.

A month later, you started talking to him. You told him about your health issues: that you eat very little (and no, you're not anorexic), that you often go to the toilet, and that you're almost always cold. You explained that this is normal and your usual state and that there's no need to be afraid, but despite this, you're positive and kind. He's the complete opposite. He's strong, loves food, enjoys sports, and is afraid of almost nothing.

This evening you were sitting with a group of friends, you were sitting in Leon's sweater, and he had his arm around your shoulder. (You were going to spend the night at Zhenya's. His parents were away. You were all sitting outside, it was evening, there was some kind of grilled food, a fire.) You and Leon were sitting on a big swing.

one of Egor's friends: aren't you hot?

Leon: Her? She's not hot, she's a bit of a cold bug.

Leon took your hand

Leon: and my hands are freezing again. Kot, should I get you a blanket?

Egor: Bro, don't you think you're courting her too much?
