• Remember in one of the New Caledonia scenes, Jan Di has a dream where a fortune teller predicts that her soulmate and her husband will be two different people? In relation, Ku Hye Sun said in an article published on March 28:
  “Ji Hu is Jan Di’s soulmate. She likes him as a person and as a one-of-a-kind, invaluable friend, although she doesn’t love him. Love can only grow when two people’s hearts are the same, but Jan Di doesn’t have those feelings towards Ji Hu.”
  I suppose that is the drama’s interpretation of “soulmate”; hence, it’s not supposed to be a bad thing that Jan Di’s soulmate and husband are two different men.
• UNCONFIRMED RUMOURS: Yi Jeong goes to study abroad over the fast-forwarded years. In the four-years-later ending, Ga Eul is teaching at a kindergarten. Apparently, Yi Jeong comes to find Ga Eul at her workplace. Eyewitnesses are claiming that the boy who plays the young Gu Jun Pyo was one of the children there, but had straight hair instead of curls.
  KP’s note: Our guess is that Yi Jeong pays Ga Eul a visit after returning from his trip abroad. We’re not quite sure why they used the same child actor for a different role. He’s too old to be Jun Pyo and Jan Di’s child, so don’t get your hopes up. ^^

Update (3/26, 3/24):

• The “___ years later” is indeed FOUR years later.

• The last scene BEFORE fast-forwarding four years ahead is Jan Di and Jun Pyo’s kiss in the Namsan cable car on the day of her graduation.

• What sparks Jun Pyo to regain his memory of Jan Di? She does pack a lunchbox (eggs and rice) like before in order to try triggering his memory - however, Yu Mi takes credit for making it so it doesn’t help Jan Di at all.
  Our source gives hints regarding what actually does trigger his memory to return:

1. Jun Pyo and Jan Di’s first kiss - NOT the one on the swing at the playground
2. New Caledonia
3. Jae Gyeong’s resort
4. Jun Pyo’s trauma
   KP’s note: Our guess is that Jun Pyo saves Jan Di from drowning.
   

• SoEul (Yi Jeong and Ga Eul):
  Apparently, the date scene at Namsan is NOT in the before-4-years-later script that our source has. Hence, he/she is GUESSING that it is part of the “4 years later” ending.
  The last SoEul scene before the fast forward is Yi Jeong opening up his heart slightly to her. All signs seem to point to a happy SoEul ending!

Kim Min Ji (Empress Chun Chu, That Person Is Coming) has been cast as Jung Yu Mi (Umi from HYD).

Kim MinJi as Jung YuMi

Yu Mi uses lies to try to widen the drift between Jun Pyo and Jan Di during his memory loss (of Jan Di). She will appear in the latter half of episode 24. Apparently, she is a character that is sure to universally annoy all viewers - she refers to herself in the third person (”Yu Mi is …. Yu Mi wants….”). Our source says that viewers need not worry too much, Jun Pyo doesn’t pay that much attention to her.

• For those of you who have been asking about the possibility of another extension - no, they will not go past episode 25 on March 31.

• Also, for those of you waiting for episode 25’s script to be leaked - the cast was given their copies of the final script on March 24. HOWEVER, the script did not include the ending (approximately 10 scenes). The creators have decided that nobody will know what happens at the end until the day they film the finale. On that day, each cast member will receive a copy of the ending to memorize immediately. It has been confirmed that Boys Over Flowers will end happily, but it may differ from Hana Yori Dango’s ending. Our source says he/she will likely get the script by Monday, but for the sake of not spoiling the ending for everyone, will NOT reveal how it ends.

• Ga Eul and Yi Jeong’s “date”:
  There are conflicting reports on whether the scene at Namsan was a BOF date scene, a BOF fake scene, or a CF shoot. Yi Jeong shows up at the porridge shop and goes to Namsan with Ga Eul. First, they discuss the sudden disappearance of Jan Di. Then, Yi Jeong says he wants to say something to Ga Eul. However, she cuts him off and tells him not to feel burdened - she will leave him alone from now on and she doesn’t regret anything that happened with him because she tried her best. From there, she leaves alone. —- HOWEVER, this does not make sense with the fact that she was wearing bunny ears and they were having fun together.
• The reason for Jun Pyo’s memory loss is in episode 24:
  He takes a blow that was directed towards Ji Hu - the man had a vendetta against Shin-hwa and tried to stab Ji Hu, thinking that it was Jun Pyo.
• Ji Hu fans beware - he is going to be temporarily miserable:
  a) His grandfather is sick.
  b) Jan Di rejects him. (It is being assumed that he tries proposing with the ring - not confirmed.)
  c) Jun Pyo gets hurt on his behalf.
• KP’s prediction was right in that the drama will end with a “__ years later” scene:
  However, the ending has yet to be confirmed and the script for episode 25 is not available.
