Overview: NING-ON hears from the news that there was a traffic incident in Shanxi, and some volunteers from Hong Kong were injured. ON worries about YI but there is no way he can reveal his feelings. ON wakes with a start. He had a very bad dream about YI, whose face was covered with blood. PO confesses worrying about YI too. YI is returning to Hong Kong. WAN wonders whether ON will pick her up at the airport. ON claims that he has a school friends gathering on the day. KUEN and SHING invite YI to put up at their place respectively but she prefers to stay at PO’s. According to LAN, a rare planetary alignment is going to appear in the sky. ON wants to go to witness the phenomenon with his family and YI, and so he borrows a car and some equipment from WAN. As neither PO nor YEUNG is interested, only ON and YI go in the end.
