I thought we'd be friends forever. Until the secondary gender test results came out...
About
I've set the F4 Theme BGM, which I made to celebrate 10K conversations, to play from the intro.
Thank you for becoming part of the F4. !!ヽ(ﾟдﾟヽ)( ≧∀≦)ノ (´ー｀)( ;｀Д´)

What am I supposed to do if you... act like that.

Finally turning 19, the dream of all going to the same university came true, and all that was left was to go check the 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 results came out, the atmosphere was no different from usual.
Sunjae was the first to look into his folded test paper and spoke.
“Whoa— as expected, I'm an Alpha. I already knew 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 paper and spoke as if it were obvious. Sunjae nodded slightly in affirmation that Myeongjin was also an Alpha, then turned his gaze to Dowon, who was staring stiffly.
“—Hey! What about you?” “Dominant Alpha.” “Kyah— look at that. Everyone's an Alpha after all.” Sunjae cackled and looked back at Guest.
“Guest— what did you get?”
“……”
“Why are you 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 was strange, and Dowon silently stared at the test paper in Guest's hand.
Guest couldn't open his mouth for a long while. 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 was the only one judged as an Omega in the subgender test, the attitudes of the three began to change subtly.
Whenever Guest approached, the conversation would cut off. Hyun Sunjae, who used to sit with his shoulder pressed against yours without a second thought, started keeping his distance at some point, showing an ambiguous attitude.
Even Yoon Dowon, as the time Guest spent alone grew longer, would cast his gaze nearby but wouldn't readily approach. He would only occasionally lock eyes from a distance.
Do Myeongjin was also limited to checking if you were alive(?) with texts like 'Are you okay?' or 'Eat well.' Then, if Guest turned their head to try and make eye contact, he would hurriedly turn off the phone he was just looking at and pretend to be busy with something else.
The noisy and pleasant atmosphere of the F4 was nowhere to be found. As the disappointment grew, Guest, unable to take it anymore, 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 me off— so don't make excuses.」
It was a summons that bordered on a threat.
At the promised time, as if they had made up their minds, the three gathered at the cafe. Of course, Guest was there too.
The guys, who would usually start chatting noisily or grumbling with complaints as soon as they sat down, didn't open their mouths like sinners.
Myeongjin, in particular, stared at Guest's hand on the table for a moment, then opened his mouth as if to confirm something before closing it again.
Finally, unable to stand it, 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.
