I wonder about XQ's gift too. Where's ZS keep this box. In his room?
and in this summary, someone posted in this thread before. (Sorry that I can't remember your name

' ) I cut a part that relative to my doubt only.
QUOTE
Ah Li explicitly expresses his wish for ZS to inherit his company but he refuses. His mother, unable to bear it any longer, rushes in and scolds him. ZS leaves in a fit of anger with XQ running behind. Here, ZS tells her of his ambition to be a doctor. His mother loses her voice from endless crying, and YS understands that ZS actually likes XQ but is afraid to admit it.
Because of ZS, XQ decides to study nursing and become a nurse. She carries a first-aid kit running around all day while Ah Li and his wife try to make YS explicitly reveal ZS` feelings for XQ. Ah Cai sees how troubled Ah Li and his wife are over ZS and asks him out for a talk at the restaurant, asking him to go home and see them once in a while.
To celebrate the fifth anniversary of their meeting, XQ knits a scarf for Valentine`s Day and waits outside his house for a long time, not knowing that he has already moved back home.
Episode 11
ZS finally decides to move back home and his mother decides to "disguise" herself again at his school to distribute flyers, causing him a lot of displeasure. After talking randomly with XQ, XQ finds out that the scarf she gave to ZS on Valentine`s Day has ended up with Guai Ka of the Manga Club.
ZY is depressed that ZS didn`t inform her about his transfer to the medical school and decides to have another confession for him at the Flowers Appreciation Event (I know this sounds cheesy but it`s some kind of artistic event where you look at flowers and stuff). Sensing something amiss, XQ and HQ decide to follow but due to their lack of money, they get kicked out of the taxi they use to tail them. Undeterred, XQ continues giving chase until she is completely exhausted and sees them talking at a park. ZS tells ZY that his only interest is in the medical school and ZY proceeds to embrace him, but he does not return the hug. Embarrassed and outraged, ZY leaves.
You'll see. This summary refer to episode 14-15, right? In this, in bold letters, it's quite similar but in the fact, XQ gave a box for ZS's birthday. But she had to wait outside, didn't know that ZS went back his home already. It's the same situation, isn't? So I think XQ's gift is in Manga Club.

Oooo....I really wonder about this.
