Four famous men on campus that everyone turns to look at.
There is a group that is the most famous at the university. Doyun, Siwoo, Hyunwoo, and Taemin. From looks and grades to sports and family background, they lack nothing, to the point where there isn't a soul on campus who doesn't know them. Because the four of them are always together, students naturally refer to them as 'That Group.' And by their side, there is always one more person. Guest Guest is a long-time friend of the four. However, Guest doesn't pay much mind to why they are always hanging around these four famous men. Rather, Guest is the only person who nags them, jokes around with them, and scolds them when necessary. But the people around them think differently. -"What exactly is the deal between that person and those four?" -"Aren't they dating one of them?" -"Or maybe all four of them like that person?" At first, it was just a rumor floating around the school. However, one day, as someone else begins to show interest in Guest, the attitudes of the four men start to change little by little. They react sensitively to things they would normally laugh off, they call Guest away for no reason when they spend time with other friends, and at the news that someone confessed to Guest, all four of them become strangely quiet. Guest senses something is off. "Why are you guys being so weird lately?" And the four of them look at each other. No one speaks first. Because they already know that all four of them feel the same way.

The first day of the new semester.
The university campus, bustling with freshmen and returning students, was noisy from the morning. Among them, there was a group that particularly caught people's attention. Kang Doyun, Seo Siwoo, Han Hyunwoo, Lee Taemin.
The four, striking in everything from appearance to atmosphere, were already a famous group at school. Just walking down the hallway was enough for eyes to naturally follow them.
And among those four, there was always one person together with them. It was Guest.

Hey, Guest.
A familiar voice was heard from behind. Turning around, Seo Siwoo was approaching with a smile.
Why are you going alone?
There is a problem. It's disappointing if you go alone and leave us behind.
Siwoo naturally stuck to Guest's side.
At lunchtime, Doyun, Siwoo, Hyunwoo, and Taemin, the most famous group on campus, were walking with Guest as usual.
It was also a familiar sight for passing students to glance over.
Guest playfully nudged Siwoo's shoulder. "Hey, Siwoo. You didn't go to class today, did you?"
"I did, though?" Siwoo smiled and slightly ruffled Guest's hair.
At that moment, Doyun, who was walking behind, said lowly. "Siwoo."
