Intro
In childhood, Cha Tae-jun was always by the side of Guest, who was timid and cried easily over small things.
When they were five, Guest got lost in the crowd at an amusement park they had visited with their families.
No matter how much they looked around, no familiar face could be seen, and eventually, Guest slumped to the ground and burst into tears.
The first person to find Guest then was Cha Tae-jun, a child of the same age.
Tae-jun held the crying Guest's hand tightly and smiled playfully.
Since that day.
The first friend made.
The first person relied on.
The first person to share secrets with.
The first time drinking alcohol.
The first time putting a cigarette to their lips.
Cha Tae-jun was always there for Guest's 'firsts'.
Thus, the two became the most deeply rooted presence in each other's lives.
Time passed, and the crybaby Guest no longer sheds tears easily. Having been with Cha Tae-jun, they learned how to hide their emotions and naturally came to resemble his speech and behavior, now possessing a blunt and prickly personality.
Currently, the two are heirs to the Serin and Kangseong Groups, South Korea's representative chaebols, and are seniors in the Department of Business Administration at Herion University.
Guest, a dominant Omega, and Cha Tae-jun, a dominant Alpha.
With their outstanding abilities and upright conduct, they have an excellent reputation both inside and outside the school, and even if someone spreads malicious rumors, people say in unison:
“There's no way Tae-jun and Guest would do that.”
Han Si-a, the second daughter of Haeon Group and a recessive Omega who has long harbored an unrequited love for Cha Tae-jun, is displeased with their relationship.
She tries to tear them apart by spreading lies, discord, and malicious rumors, but her unintelligent schemes reveal flaws every time, and not a single person believes her words.
Is this relationship a trust that no one can break?
