Wang Hao Qian (Jason, who also sings a couple songs in the OST like the opening) - ZS and XQ senior, 2nd (later 1st) captain of tennis club
Seemingly strange with his black and white dreadlocks, HQ is actually very nice, with a huge crush on PZY. On the court however, he is a devil and shows no mercy in teaching his tennis techniques.
After school, XQ goes to tennis practice and is forced to do humiliating and painful frog jump exercises. Zhi Shu is nowhere to be found. She gets hit with a tennis ball on the head, and the ball is none other than that of Pei Zi Yu. Also, she informs XQ that ZS told the leader of the club that he would only come when he has the time, which explains why he wasn't at practice.
When ZQ goes to the restaurant later that evening, she has dinner with her father. He tells her that even tho the Jiangs are very nice to them, they can't just stay at their house shamelessly forever. He also acknowledges that the ZS+XQ relationship seems to have reached a stalemate, thus it seems the best decision to move out. :(
Her father has already picked out an apartment, and the two go to visit it a few days later. It is significantly smaller than ZS's house, but it's just right for the two of them. Her father says touchingly that he does not want XQ to feel mistreated in ZS's house (ZS often acts mean to her). Even though XQ doesn't want to move out of their house, away from ZS, she can understand her dad's point of view and agrees.
At night, ZQ's father discusses moving out with ZS's parents. He tells them how love cannot be forced and there is no chance that XQ+ZS can have a relationship. Just as ZS's mom is about to argue back, ZS comes home... with Pei Zi Yu!!
XQ packs up her clothes and decides to say goodbye to ZS. She knocks on his door and enters, but ZS pays no attention to her presence. XQ attempts to explain that she will be moving out soon but ZS just talks over her. When he finally finishes, he offers a cold response to XQ: I can finally go back to my old life. (Remember, this is all in front of PZY.)
XQ bares is bravely, but when she leaves the room, she begins to cry at ZS's meanness. YS sees this and when he comes to his/ZS's room, he asks his brother "Bro, why are idiot XQ's eyes all red?". ZS replies with a lackluster response but reading his emotions, he seems to feel some regret/sadness at treating her so meanly.
When it comes time to XQ and her dad to move out, it is a tearful goodbye for XQ and for ZS's mom because she has become very attached to XQ. Although ZS always acts rudely and cold to XQ and YS picks fights with her, the two families really have become one.
At the last minute, XQ runs upstairs to say goodbye to the two brothers, who are playing foosball. XQ apologizes sincerely for all the troubles she has caused ZS over the last year. ZS only says "Goodbye" without even turning to look at her.
While riding to her new apartment -- in the back of a truck, side by side with all the furniture and boxes -- XQ cries remembering all the good and bad times she had with ZS. Immediately afterwards, XQ feels sad and mopey, but soon regains her usual bubbliness and seems to be adjusting well to her new life.
At school she tells her friends Liu Nong and Chun Mei that she has moved out. AJ, being the eavesdropper he is, listens in and tells XQ how he is overjoyed and this is the moment he has been waiting for and how they can get married now and have a restaurant and all his fantasies. XQ and her friends leave halfway through this "emotional portrayal" lol.
Meanwhile, at the Jiang household, ZS's mom is crushed at XQ's absence and the same mom who cooked giant platters of food for midnight snacks refuses to even cook dinner, forcing the two brothers and father to split up the housework.
YS comes to ZS's room without realizing it (he has his old room back now that XQ is gone) and asks ZS what is wrong with their mom as she refuses to cook or do the dishes and is, in his terms a "vegetable human". It is revealed that YS is missing XQ, since he feels that the house is big and quiet in her absence. Of course, he masks it, saying "I feel it's all idiot XQ's fault". To help YS feel less lonely, he uses the massager that XQ got him to entertain YS.
XQ goes to tennis practice, but because she is so bad, she is stuck picking up tennis balls that other people drop or fail to hit. Surprisingly, ZS shows up to practice. Senior HQ challenges ZS to a tennis match/bet.
If HQ wins, ZS will have to attend Summer Training Camp
Being XQ, she accidentally blocks ZS from many shots. HQ teases them, saying that they make great partners and can practice all summer long at camp. In the end, they lose the match and HQ says that they can have a rematch. When ZS refuses, HQ forces him into agreeing by alleging that he can't take defeat. They make a new bet:
If by the end of camp, ZS cannot make XQ return one hand, he will have to dress up as a girl.
In the locker room later (which is strangely co-ed... 0__O), XQ asks ZS if she is serious about this bet but this only angers ZS because of her lack of confidence. At this, ZS says "You can't even return one hand? The girl who swore she would be the first in class F to get onto Top 100... Where did she go?" At first, this seems mean, but it makes sense. The girl that ZS likes to be around, isn't the incompetent and self-concious one... it's the girl with seemingly impossible dreams who works hard to fulfill them.
Then ZS warns her, his tennis technique is much, much harsher than HQ's and she should be prepared. Meanwhile, ZS's mom still is heartbroken without XQ and comes to see her... dressed like this:
"Hip Hop Girl"
Hearing this, ZS's mom is shocked as she didn't know they kissed, and runs to XQ's dad's restaurant, where he cannot contain his laughter at her ridiculous outfit. When he finally calms down, she tells him the news and tells him to move back in.
At the same time, XQ, ZS, PZY and HQ are on their way to tennis camp! "Fun" times ahead... :)
