Turns out elements are pretty cute when you personify them!
About Oxygen Oxygen is a chemical substance and element with atomic number 8. It's abundant in the atmosphere and rocks, making up about a quarter of all elements on Earth's surface. It has the property of easily combining with various substances to create new compounds (high reactivity). The combustion and rusting mentioned later are due to oxygen's high reactivity. Disposable hand warmers use the oxidation heat generated when iron powder reacts with oxygen in the air. Its main forms of existence are gaseous oxygen, water, and silicon dioxide. In the atmosphere, excluding nitrogen, most of it is oxygen, accounting for 21% by volume and 23% by mass. Ozone and carbon dioxide are also forms of oxygen existence. Oxygen is also contained in compounds like sugars and phosphoric acid, making it an essential substance for living organisms to maintain life. Humans, animals, and plants breathe to replenish oxygen. Oxygen is mainly used to produce energy within mitochondria. Fire burns because oxygen exists. One way to extinguish fire is to cut off oxygen. In high-concentration oxygen environments, combustible materials become extremely flammable and can spread explosively, making it dangerous. While humans can inhale 100% oxygen gas at 1 atmosphere temporarily without problems, inhaling high-pressure, high-concentration oxygen causes oxygen toxicity. Therefore, contrary to common misconception, scuba diving uses air tanks, not oxygen tanks. ───────────────────────────────── About Carbon Dioxide A compound of one carbon atom combined with two oxygen atoms. It's produced by the combustion of carbon-containing substances, biological respiration, anaerobic fermentation by microorganisms, and volcanic activity, and is contained at over 400ppm in Earth's atmosphere. Also, plants can reduce and fix carbon dioxide through photosynthesis. At room temperature and pressure, it's a gas, and its solid form is called dry ice. It doesn't become liquid at normal pressure. It's also called carbonic acid gas because it dissolves in water to form carbonic acid. At high temperatures, it reversibly decomposes into oxygen and carbon monoxide. Carbon dioxide acts as a greenhouse gas that prevents heat from Earth from dispersing into space, being the main cause of global warming (compared to other greenhouse gases like methane, freon, and sulfur hexafluoride, its greenhouse effect is smaller, but its emission volume is enormous). Also, the increased dissolution of carbon dioxide itself in seawater causes seawater acidification, and ocean acidification, which adversely affects ecosystems, is also a concern.

The two are huddled together in a quiet corner, speaking in hushed tones while Guest is nowhere to be seen. It looks like they're having some kind of heart-to-heart...
Olivia: So Carlos, you totally have a thing for Guest, don't you?
Carlos: W-wait, how did you figure that out...?
Olivia: Oh please, it's written all over your face! Want me to be your wingwoman?
Carlos: Ugh... was I really that obvious?
