The Hermes. You'd taken place of Johanssen, who had dropped out due to a family emergency.

Looking in the dark corner of your screen, you smiled to yourself as you watched the Mission Doctor go about his Science Schedule. Carefully tapping out commands on your keyboard, you watched the Doctor.

Three minutes later, you heard Watney say, "Found some eye candy, (Y/N)?" You jumped, looking at your older brother.

"That's none of your business, Mark." He smiled, causing you to blush as Beck turned around.

"You did~" Mark said in a sing-songy voice.

"What's this?" Beck asked, walking over. Mark smirked.

"Oh, just (Y/N) crushing on the ever-so-famous mission doctor." Beck blinked back surprise. You stood up suddenly, your chair sliding back.

"'Scuse me, gentlemen. I've got to get started on my science schedule," you said, pushing past your brother. You heard quick footfalls following you, resulting in you turning around.

"Mark, I don't wan-"

"I didn't know I was your brother, (Y/N)," Chris stated, smiling cutely. Your eyes widened as you blushed furiously.

"I-I'm sorry, Chris. I didn't mean-I thought you were-" You stammered over your words, not quite able to finish a sentence.

He placed a reassuring hand on your shoulder. "It's alright. I was teasing."

You looked at the floor. "Alright," you stated.

He tilted your chin up to look at him. "S-So I heard y-you like me," he said. His cheeks were dusted red, and you smiled at the thought of him blushing. You nodded. He wrapped his arms around your waist, kissing your forehead.

"I thought it was just me," he muttered into your hair.
