Even though both characters have cool styles, the overall vibe between Ryu Seon Jae in Lovely Runner and Ryu Shi Oh in Strong Girl Nam Soon is very different. Ryu Seon Jae is portrayed as a sweet, idealistic schoolboy who eventually becomes an idol, whereas Ryu Shi Oh is depicted as a rich, fierce CEO.

These roles showcase Byeon Woo Seok’s versatility as an actor. As Ryu Seon Jae, he embodies a softer, more approachable persona, whereas Ryu Shi Oh is intense and commanding. This stark contrast raises the question: which character do fans prefer to see him play—a gentle idol or a powerful CEO?

The Different Auras of Byeon Woo Seok

One of the most noticeable differences is in Byeon Woo Seok’s eyes. In Lovely Runner, his gaze as Ryu Seon Jae is tender and warm, especially when looking at the female lead. This softness can melt the hearts of viewers. On the other hand, his eyes as Ryu Shi Oh in Strong Girl Nam Soon can be quite intense, reflecting his more ruthless and determined nature.

Despite these differences, there’s a common thread: Byeon Woo Seok’s ability to convey deep emotion through his expressions. Whether he’s playing a sweet character or a fierce one, his gaze holds a captivating charm that draws viewers in.

When comparing these two characters, some netizens refer to Ryu Seon Jae as a “green flag” and Ryu Shi Oh as a “red flag.” This means that while Ryu Seon Jae represents an ideal partner, Ryu Shi Oh is seen as more of a warning sign—intense and potentially problematic.

So, which role do you think suits Byeon Woo Seok better? Do you prefer his portrayal as the endearing Ryu Seon Jae or the formidable Ryu Shi Oh? Both roles highlight different aspects of his acting talent, making him a truly versatile actor.
