A man’s intuition is really strange.

I returned to the dormitory that day and caught a whiff of a familiar Omega’s pheromone as soon as I entered the door. That was the kind German used to be smelled like. He said it was his brother’s.

There was a young boy sitting on German’s bed. His facial features were very beautiful, but no matter how hard I looked at him, I can’t see any resemblance between them two.

He somewhat arrogantly crossed his arms and legs on the bed, “You are German’s roommate?”

The tone in his voice caused me to feel some dissatisfaction. I resisted my inner irritability and replied, “Yes, hello. My name is Alvin.”

“Hello, Alvin.”

He didn’t gave me his name back and that was very rude.

“So German is back? Are you his brother?”

He looked up at me and has an uncomfortable ridicule on his face, “He told you that I am his brother?”

…?

I haven’t started to ruminate on that in my mind, and German has already opened the door to come in. He did not wear his training clothes. That means his training did end two days ago. He carried a big bag of stuff in one hand and his smart device in the other hand. He didn’t look around to see if there’s anyone in the room, and just threw the bag to the Omega on the bed.

“I have queued for three hours, alright?”

His face has a very lively irritated expression, completely different from his usual mask-like emotions on his face when facing me.

German looked up and saw me standing by the side inside the room. He quickly stepped forward and hugged me.

“Al? I have not seen you for a month now.”

My arms went around him and I hugged him as tightly as I could when he was still holding me, and immediately loosened my grip when he let go, so that it won’t be embarrassing.

“……En.”

The third person in the room coughed twice. “Alright, German, you told Alvin that I am your brother?”

German frowned, and let go of me. He then said to me, “This matter is not easy to explain. We are in a hurry now and I’ll come back at night to explain.”

I nodded. He picked up that noisy Omega and smiled with a bit of ridicule, “Hurry and go, don’t blame me if you couldn’t make it.”

The two of them bantered while pushing each other out of the dormitory. When he is about to leave, German turned back and said, “Wait for me to come back.”

The Omega also turned back and smiled at me. When he turned around, I could clearly see a slightly reddish, bite mark at the back of his neck, as his shirt slightly slid down from being pushed by German.

That was a temporary ‘marking’.

After they went out of the dormitory, I almost immediately locked the door and rushed to German’s bed to identify the pheromone’s smell. Then I touched my smart device to check the pheromone’s lingering time.

[It is generally believed that Omega’s pheromones will stay in the air for about ten minutes before completely diluted to an indistinguishable degree. It is about half an hour in a relatively closed room and clothing that absorbs odor molecules.]

I changed the question to ask how long does the pheromone stay after a temporary marking?

[For a couple of AO1 that has yet to complete the final permanent marking, a temporary marking will let the pheromone stay for 2-12 hours in the air. The pheromone of a couple that has completed the final marking will linger for 1-6 months after any contact.]

Um… it means…

That so-called ‘brother’ is actually his boyfriend.
