It starts off where Aishen is teaching the girl how to rollerblade but then suddenly, men in black (Yakuza, not the Will Smith type) tries to kidnap her but Aishen defends her and they managed to escape and hides with her at the gang's hideout. The next morning, Beck and Wang Xing are at Yu Yayu's house trying to wake him up to see what had happened to Aishen. When they arrive, there is a small explosion in the hideout and Aishen comes out, covered in soot and looking like a crazed man screams, "SHE'S GONE!" and bangs his head on the side of the bus (Which is their hideout) He says that if only he hadn't fallen asleep, they wouldn't have caught her.

They managed to track the mafia down and they had to fight their way through the bosses bodyguards. They fought all the way untill the chapel were the japanese girl was about to marry a japanese guy. They are a Yakuza triad. By the way, the japanese guy has no looks compared to Aishen. Anyway, they tried to stop the wedding but the girl says that she does not know them and they were forced to leave. But while she was being wed, she said this in her thoughts, "I'm sorry Aishen... This is for your own safety. I'm very sorry."

Heartbroken, Aishen retreats back to the hideout and starts inventing things (He does that everytime he's upset.) While Aishen is sulking, Yu Yayu, Wang Xing and Beck discuss their loyalties and they would always stick together.

That night they went to the doctors to have their bandages removed and they had no scars. They were so relieved. And I guess Aishen managed to get over the japanese girl. Anyway, Yu Yayu prepares for his operation to remove the glass shard in his eye. His mother was about to tell him who his father is but starts crying. He tell her that its ok if its too painfull to tell him who his father is but she insists. But just as soon as she was about to tell him, none other that Yuli comes in. Yu Yayu mother cries even more and runs out of the room. Yuli thought that he bullied his mother and scolded him but he explained to her that she was about to tell him who his father was. Yuli wanted to get Yu Yayu's mother back but he told her it wasn't really important now, since at this point he might loose both eyes. Well, Yuli and Yu Yayu talk and she tells him that she would always support him and be there for him (Actually she said lots more but I can't remember.) Yu Yayu is touched and then for the first time, he sheds a single tear. And true enough, the glass shard came out.

Both of them were so happy thet they left to find Yu Yayu mother. But when they found her she was being helpped by Yuli's father. She says that she has been looking all over for him while raising his son.... Yu Yayu...

Summary
After seeing what had happened... I got really teared up. Because for the past 10 episodes, I could feel thet Yu Yayu and Yuli were bonding and falling in love for one another... only to realize that their love is forbidden...
