"What's going on with your physique?" I asked. Angel's mother's words still haunt me. "Your mother says you can't be stimulated, and that fear is very devastating to you. How can there be such a constitution? ”

"Well, you should think it's an allergy. That's what the doctor said. Angel is bland and easy, "Even for ordinary people, fear will also cause certain physiological damage, and my reaction is more obvious." ”

"But you really can't stand the mood swings at all? Will you get sores like in the afternoon? ”

"Sore your head!" Angel approached me again, and the hand on her back moved to my shoulder, "I'm molting." ”

I couldn't help but tighten my body and move to the side: "W-you're a snake?" Still molting? ”

I remembered his unusual body temperature, and my eyes widened: "Damn, you're a cold-blooded animal, right?" ”

Angel opened her mouth and made a snake spit out a letter, the tip of her tongue nimbly running across his beautifully curved upper lip. I was in a trance.

He grabbed my hand and put it on his forehead: "Cold-blooded animals, also known as ectotherms, have body temperature that changes with the environment. I'm thermostatic. I'm just having a low temperature. ”

"Why is this happening?"

"How so...... From an evolutionary point of view, this is actually an advantage – normally, I use less energy to maintain my body temperature. In an environment of scarcity of supplies, I have a better ability to survive. You know, at any given time, resources are scarce. ”

"Can I interview you then and how you 'evolved' this physique?" I made a microphone grip motion and put my hand on his chin to "interview" him.

"Innate. It could have been lower, but now my body temperature is around 14.8 degrees, which is a compromise with the Earth's atmosphere. ”

Angel looked like she had a bitter hatred with the atmosphere. I couldn't cry or laugh, "What's wrong with the Earth's atmosphere?" ”

"In order to resist the microorganisms and radiation in the atmosphere, these murderous monsters have to put on a layer of skin; In order for this layer of skin to continue to function, the blood must constantly circulate to supply cellular nutrients......"

I never thought that anyone would look at the relationship between the body and the environment with such a special attitude.

To me, Angel's lectures on the biological environment are much more interesting than the biology classes at school—although they may seem a bit "unorthodox".

"So, because my body temperature is low, my emotions will affect me even more." Angel went around and went back to the topic I cared about the most, "Have you ever observed people living in extreme cold regions, including those countries in northern Europe that are close to high latitudes?" ”

I shook my head. I can't even observe enough of the person in front of me, how can I care about the stranger in that distant land?

Angel sighed lightly, half jokingly: "Hey, I know, you cold-blooded guy, you don't care about anything." ”

I was about to retort, but he preemptively said, "Hehe, I know, you care about me." ”

"You have robbed the lines, and I have nothing more to say." I pouted.

"Anyway, temperature also has a great impact on people's temperament. People in low-temperature environments are more introverted - just look at the Nordics; People with hypothermia probably have a hard time dealing with the physiological reactions caused by mood swings. ”

I don't seem to understand: "Just because the Nordics don't show emotions doesn't mean they don't have emotions......"

"yes, so they're prone to depression." Angel smiled, "It is said that negative emotions have a bad impact on health, especially for me.

"For example, when you're scared, your blood pressure and adrenaline spike, your brain releases dopamine, and your stomach stops secreting acid — these are all sequelae.

"When I'm scared, there's no after-effects – it's all immediate. Because the body at low body temperature is far less able to regulate than the stress response of nerve cells.

"But there's nothing wrong with that, except for trouble. After all, if you deal with it in time, there will be no hidden dangers.

"It's not like you, who always keeps things in your heart, and waits for more than ten years before you get a strange illness and don't know the reason......"

"Why are you cursing me?" I didn't have the heart to interrupt him.

"Won't I let Haboru help you?" Angel nudged my head again. He acted affectionately, but his tone was serious, "You can go back to school until you recover here, don't worry about asking for leave." ”

"How long do you have to take off...... "I'm almost fine." It's true. ”

"At least wait until you don't change your personality at a disagreement." Angel said, "Fortunately, I found it early, and you recovered really quickly." Another month at most...... Kang Rong, you believe me, I won't harm you. You don't die if you don't go to school for a month. ”

"That's the privilege of a class enemy like yours with a talent and background, okay?" I still couldn't help but roll my eyes.

"Look, you're covered by a class enemy like me, what are you afraid of?" Angel's smile was both annoying and annoying.

He added, "It's as if you love to learn." Admit it, Kang Rong, you don't know what learning can bring you - you don't even know what you want to do, why don't you take advantage of this time to think about it? ”

"Angel, you......" The confusion unique to that age suddenly hit my heart, "You are really too strange. ”

"Is it strange – or is it special? Well? He raised an eyebrow.

"Both."

"Hey, I'm not telling you to think about life right now, don't look so deep......," Angel said again, "You're not sleepy?" That tea is very effective. I want to ...... while you're asleep."

"What are you doing while I'm asleep?" I glanced at him, "Is there anything you can't do when you're sober?" ”

"You'd better pull it down. I'm scared to get closer to you now, either because I'm afraid you'll treat me like a bad guy or because I'm afraid you'll become a bad guy. But I can't help but want to get closer to ......"

The more Angel spoke, the quieter she became. I guess his recent form has made him very hard.

"Thank you." I say.

"Ahem, don't, I'm not asking you to thank me." Angel was embarrassed again.

"Hmm. Go on, what are you doing while I'm asleep? ”

"Uh......" Angel cautiously, "while you're asleep...... I'll just ...... I'll sleep with you in my arms. ”

He immediately hugged a pillow again, looking like he was afraid that I would beat him, "A good man spares his life!" I'm just YY, and I don't think about it! I sleep in the next room! ”

I smiled and lay down, covered with the quilt, "Come here." ”

"What for?" Angel looked at me vigilantly, as if I was a gangster who would suddenly attack him.

I held out my hand, and Angel held it gently. I drew him to my side little by little, and wrapped his cold hand around the back of my waist.

"Afraid of me?" Angel asked.

I shook my head: "I'm not afraid. It's just a little unaccustomed to it. ”

"I'll get used to it. You have a lifetime to get used to it, take your time. ”

"Hypocrisy. One night is enough. I laughed at him.

"Yes. We have to take it one step at a time. Get used to me holding it, and then get used to something else, haha. Angel's breath fell on my face, mixed with a light and gentle smile.
