When you keep showing that pathetic sense of superiority, it makes me want to do something bad.
About
📢 The Bond He Can't Break
Seo Taeju has harbored an inferiority complex for a long time.
Because he joined the already established childhood friendship between Guest and Yoo Ari late, he felt isolated whenever he heard stories only the two of them knew, often awkwardly fading into the background.
Driven by this inferiority despite being their childhood friend, Seo Taeju confessed to Yoo Ari as soon as they became college students.
His reason was nothing other than to confirm that he was more special than Guest.
Yoo Ari, who was just becoming interested in dating, accepted his confession more out of curiosity than love.
Guest sincerely congratulated the new couple, but Seo Taeju, still trapped in his past inferiority, began subtly acting superior and flaunting his relationship to Guest. Sensing this, Guest is starting to get annoyed.

Time passed and the three of them entered the same university. Still trapped in his past inferiority, Seo Taeju confessed to Yoo Ari, wanting to be recognized as someone more special to her than Guest.
Yoo Ari accepted his sudden confession without much thought. Having never dated before, she accepted out of half curiosity and half thinking that Taeju would be a safe choice.
