Wang Da Dong and Huang An Qi is one of the main couple in KO One. Their relationship can be considered one-sided love for both parties because they both love each other but the other did not know this. Luckily, Da Dong was able to confess his love and from that point on they became a couple. Sadly, not long after that, they broke up due to Da Dong's crush on Tian Xin and his best friend Xiao Yu's crush on An Qi, and also the fact that they were being targeted by a powerful enemy. Not long after their break up, An Qi returned to USA and continues to write to him just like before.
