Most of the K-Dramas we watch provide us with male characters that are flawless and almost perfect at everything. They are the ones who are born into wealthy families, intelligent, and of course, have a great sense of fashion.

There are also green-flagged characters who take good care of their partners. But bad boys also do exist in every story. Though these characters are walking red flags, we can't help but fall in love when they finally show small yet kind gestures, especially to female leads.

Gu Jun Pyo (Lee Min Ho) 'Boys Over Flowers'

His iconic role as Gu Jun Pyo in the classic K-drama "Boys Over Flowers" screams lots of red flags. Tall, rich, and handsome, Gu Jun Pyo is one of the bullies in their school.

He always gets what he wants, not until he met Geum Jan Di. All the negative traits he has changed and made the viewers swoon with his sincere and heart-fluttering gesture towards the woman he loves.

Park Jae Eon (Song Kang) 'Nevertheless'

Park Jae Eon perhaps is the most popular red flag character that ever evolved in K-Drama. Korean heartthrob Song Kang perfectly portrayed the playboy role and just like the series' female lead Na Ba (played by Han So Hee), the viewers too were confused about whether to hate or love him. He is a big red flag but too hard to resist.

Both lead characters fall into a lustful relationship, but as time passes by, Na Bi begins to wish for more. Unfortunately, Jae Eon doesn't have the same goal as her. All he can do is make her feel all sorts of butterflies, but his insincere actions never touch Na Bi's heart.

But when he finally realized who Na Bi was in his life, he underwent character development.

Jang Joon Woo (Ok Taecyeon) 'Vincenzo'

Ok Taecyeon impressed the viewers with his character transformation in the dark comedy-legal drama "Vincenzo." He played the role of Jang Joon Woo, Babel Group's president and the greatest enemy of Vincenzo Cassano (played by Song Joong Ki).

Good thing is that they showed his true colors sooner, so Hong Cha Young (Jeon Yeo Bin) got out before she fell for the bad guy.

Choi Do Il (Wi Ha Joon) 'Little Women'

Last on the list is Choi Do Il played by breakout star Wi Ha Joon in the newly concluded series "Little Women." He only cares about money, but everything changed when he met Oh In Joo (played by Kim Go Eun). Many times, he chose money over someone who had helped him not to be caught.

Even the viewers were perplexed about whether to love or hate Do Il's character. However, despite all the red flags he has, his fiery chemistry with In Joo satisfied the viewers that there's more than money between the two. He won the hearts of many with how he protected In Joo in the last episode of the drama.
