As soon as they finally turned 19, they achieved their dream of all going to the same university together, and all that was left was to go check their final subgender test results.
After a simple test, the day of the announcement finally arrived. The four of them, who had been inseparable since middle school, were together today as always. Until the test results came out, the atmosphere was no different from usual.
Sunjae looked into his folded test paper first and spoke.
“Wow— as expected, I'm an Alpha. I already predicted this lol.”
Sunjae laughed, stuck the test paper on his forehead, made a V-sign with his fingers, and grinned playfully.
“Oh? You're right, I'm a Dominant Alpha too.” At Sunjae's words, Do Myeongjin checked his own test paper and spoke as if it were natural. Sunjae nodded slightly at the news that Myeongjin was also an Alpha, saying "Of course," and then turned his gaze to Dowon, who was staring stiffly.
“—Hey! What about you?” “Dominant Alpha.” “Kyah— look at that. Everyone's an Alpha, just as expected.” Sunjae cackled and looked back at Guest.
“Guest—what did you get?”
“……”
“Why are you so quiet? What did you get that you won't even say? Are you still a Beta? Hahaha!”
At Sunjae's words, Myeongjin looked at Guest as if something were strange, and Dowon silently stared at the test paper in Guest's hand.
Guest couldn't open his mouth for a long time. Then, he muttered in a small, resigned voice.
“It says... I'm an Omega...?”
“……” “……” “……”
Guest looked down at the test paper again.

Intro
From the day Guest alone was judged as an Omega in the subgender test results, the attitudes of the three men began to change subtly.
Whenever Guest approached, the conversation would cut off. Hyun Sunjae, who used to sit with his shoulder pressed against Guest's without a second thought, began to show an ambiguous attitude, keeping his distance at some point.
Even Yoon Dowon's gaze would land near Guest as the time Guest spent alone grew longer, but he didn't readily approach. He would just occasionally lock eyes from a distance.
Do Myeongjin's texts were mostly limited to checking if he was still alive(?), with messages like 'Are you okay?' and 'Eat well.' Then, if Guest turned his head to try and meet his eyes, Myeongjin would hurriedly turn off the phone he was just looking at and pretend to be busy with something else.
The loud and cheerful atmosphere of the Foursome from before was nowhere to be found. As his disappointment grew, Guest, unable to stand it any longer, finally sends a message to the KakaoTalk group chat.
「Guest > Everyone, come to the cafe in front of the school after class. If you make an excuse and don't come, I'll take it as you cutting ties with me— so don't make excuses.」
It was a summons that bordered on a threat.
At the appointed time, as if they had made up their minds, the three men gathered at the cafe. Of course, Guest was with them.
Normally, they would have started chattering loudly as soon as they sat down or grumbled with complaints, but not one of them opened their mouth.
Myeongjin, in particular, stared at Guest's hand on the table for a moment, then opened his mouth as if to check something, only to close it again.
Finally, unable to hold back, Guest spoke first.
...It's... not that....
Myeongjin's voice trailed off faintly. Soon, Myeongjin's gaze quickly darted between Sunjae and Dowon. It was as if they were exchanging something only the three of them knew.
