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.
Da Dong has been in love with An Qi since before the start of KO One. However he was too shy to admit it. An Qi on the other hand, was also in love with Da Dong, but she never knew how Da Dong feels towards her and even thought that he hated her because he usually ran off every time he sees her. An Qi continuously writes letters to Da Dong from the U.S. but Da Dong never replied any of them. Even though she thought that he threw them away, she still writes to him. She never knew that he memorized all her letters but was too afraid to write back because he could not write very well.
After An Qi got back from US, she tried everything to get Da Dong's attention, even changing the way she looked, from a good girl to a gangster, just like Sha Jie (this was because An Qi thought Da Dong like a girl that is tough like Sha Jie).
After Lei Ke Si attacked Da Dong, she realized that her love for Da Dong almost cost him his life and ruined their friendship with Lei Ke Si. She also realized that those few years when she was in love with Da Dong, has made her disregard other people around her. Because of that she finally decided to return to USA. Luckily, Da Dong was able to stop her and confessed his love. From that point on, they became a couple.
Not long after they became a couple, Da Dong started to get jealous whenever his teacher, Tian Xin, cared more about her boyfriend than her students. Because of his jealousy, he started to neglect An Qi. At the same time, Xiao Yu became close to An Qi and An Qi then realized that he had a crush on her. Because everything that happened, An Qi and Da Dong finally broke up but remained friends.
When Da Dong and Xiao Yu (along with Ya Se) were busy dealing with Hei Long, An Qi was neglected by both of them. She then realized that she was unable to pick between the two of them because they both have special place in her hearts. So she decided to return to US, only leaving a letter to Da Dong. After she returned, she continued to write to Da Dong twice a week, just like before and they remained friends.

Seeing how busy Da Dong was, An Qi then decided not to tell him anything. After that Da Dong left with the others.
Da Dong went to help Shao Zong and forgot his plan with An Qi, so An Qi spent that day with Xiao Yu instead. An Qi bought him a necklace as his birthday present.

Da Dong said that An Qi treated him the best out of all people. Then, he promised never to forget about her again and hoped that she would not be mad at him anymore. She said that she was not mad at him, but Da Dong knew she was mad with him. He said that he would make it up for her by celebrating his birthday with her on that day, but An Qi refused because she already celebrated with Xiao Yu. An Qi then told him that Xiao Yu might like her and that she did not reject him. After hearing this Da Dong was very shocked.
The next afternoon, Da Dong asked Xiao Yu about his feelings towards An Qi. Xiao Yu confirmed that he was in love with An Qi but he willing to make sacrifices. So he let Da Dong do anything he wants to him. However, Da Dong cannot bare to hurt him and said that An Qi belongs to Xiao Yu.

She asked him to stop but he did not say anything. Not long, Xiao Yu joined the both of them and after that form teacher joined them.
Later that day, Tian Xin asked Da Dong what happened, but he would not tell her. He felt very bad that An Qi was willing to stand beside him but he ignored her. He felt even more guilty because he did not even realized that she was crying. Da Dong was tearing up when he was about to tell the truth but before he could start he sense someone very powerful with high desire to kill. Because of this, he immediately stopped and protected form teacher. After that person left, Form Teacher thought that he was doing that to avoid telling her the truth so she left and said that she was going to asked An Qi instead.
An Qi and Xiao Yu talked about what happened on the afternoon. An Qi said that Da Dong was that kind of person, he rather step back than fight Xiao Yu, just like he secretly memorizing 500 letters. An Qi said that her feelings for Da Dong would never change but she was confused on how to decide her feelings. Before they could finish their conversation, Xiao Yu felt the presence of a stronger opponent with high desire to kill. So he stopped talking and was on guard.
An Qi did not sit next to Da Dong in class anymore. Even though they already broke up, but Da Dong kept thinking about his relationship with An Qi and Xiao Yu.
When Da Dong and Xiao Yu met An Qi in the hallway, all three of them became awkward towards each other.
In class, when Da Dong suddenly felt someone powerful and stayed on guard, he told Xiao Yu to take An Qi away from there if something happened.
An Qi and Da Dong accompanied Xiao Yu after he broke his arm. Da Dong was surprised when Xiao Yu agreed to An Qi's advice and willing to stay with Da Dong. In Da Dong's bedroom, Da Dong said that Xiao Yu did not owe him anything because An Qi chose him and that was her choice. After that he was going to leave the house to look for "that person". He said to Xiao Yu that if he did not come back, he wanted Xiao Yu to take care of An Qi for him.
At class, Xiao Yu insisted that he could still fight but Da Dong told him not to act tough and asked him to take care of An Qi.
In the restaurant, form teacher asked Da Dong, An Qi, and Xiao Yu to tell her their love stories. After they heard this they became quiet and very awkward. When Ya Se was telling them his love story, Da Dong told Xiao Yu via telepathy to stay and protect Form Teacher and An Qi when the terrifying guy came.
After Da Dong got injured because of Su Huan Needle, he was unable to go outside the house. However, he still worried about An Qi and told Xiao Yu to spend more time with her.
An Qi decided to return to the US. She gave Xiao Yu a letter to give to Da Dong and said that Da Dong and him were special in her heart. She also asked him to take care of Da Dong and himself.
Xiao Yu realized that An Qi still loves Da Dong.
On her way to the airport, An Qi thought and remembered all the things involving Da Dong and Xiao Yu. While she was thinking this, she cried. She said that she did not regret anything that happened between her and Da Dong because these days that have pass were enough for her to think of for the rest of her life.
Da Dong got An Qi's letter from America (576th Letter). At first he was confused because he thought An Qi was still in Taiwan. After he read the letter, he quickly ran out off his house to find Xiao Yu and get things straight.
Da Dong and Xiao Yu laughed and talked together. Da Dong said that it had been a long time since they were very relax. Then he asked whether Xiao Yu missed An Qi or not. Xiao Yu did not answer and asked him back instead. In short, Da Dong said that he used to that kind of situation and continued to miss her. After that Da Dong asked Xiao Yu about the MC Song he asked Xiao Yu to compose for An Qi. Xiao Yu then gave Da Dong his earphone and he listened to the song.
