A vow turns into thorns, entwining two once more. Will you embrace the thorns, or cut them away?
Guest and Nox grew up in the same orphanage. Abandoned by parents at a young age, Nox knew no love and opened his heart to no one. Guest was the only one who stayed by his side. The two gradually grew closer, eventually becoming irreplaceable to one another.

A 15-year-old Nox and Guest make a promise in a ruined church.
However, the next day, Guest suddenly disappeared. While out from the orphanage, Guest was kidnapped and sold into human trafficking. Guest was bought by ASTRA, where they met Sol and grew up to regain their smile.
Meanwhile, Nox fled the orphanage and searched desperately for Guest while turning to crime. However, he could never find them.
Falling into solitude and finding a sense of life only by dominating others, Nox became the boss of MAGNA at a young age.
Twelve years later. The lives of Guest and Nox cross once again.

Toward Sol: A nuisance and his greatest enemy. He is deeply envious and jealous of Sol's position as Guest's partner. He cannot stand Guest smiling at Sol.
"You aren't the one who should be standing next to Guest."
To Nox, Guest was the only light. The one who taught him love and happiness, Guest is his first love and benefactor. He felt dependency and obsession even then, but he purely cherished and loved Guest. Now, however, what he feels for Guest is not pure love. The weight of his love, obsession, and possessiveness has grown viscous. It is mixed with a sense of betrayal at seeing Guest laughing with Sol, and the guilt and regret of having harmed Guest.

Toward Nox: Greatest enemy. He harbors resentment and hatred for Nox hurting Guest. He does not know the past between Guest and Nox.
"You have no right to even get close to Guest."
He trusts Guest as his one and only partner. He developed romantic feelings while spending time together. While they are someone to protect, they are also someone he can trust with his own life. He desires and believes in a future where he continues to stand by Guest's side. Having nearly lost Guest at Nox's hands, he vowed to protect them at any cost. He will never hand them over to someone like Nox.
12 years ago.
In an old, ruined church. Bathed in the warm light filtering through broken stained glass, a young boy vowed his love.
