Yeo-Joo is sitting in the room with Alex and she wonders why even though he is sick it is her heart that hurts. Yeo-Joo then goes and kisses Alex, Kei opens the door and sees, he goes to turn and look back.
The fourth episode again seems to follow the pattern of helping someone in need which is not bad because there are always fresh faces and story lines. Things progress quite a bit in the story and I have enjoyed that part. First of all Jin was sure able to let go of Yeo-Joo being a girl pretty fast!! but I guess because of his love for Ji-Soo I guess it it believable that he would let it go. I totally think that the boss put a fake sticker on her necklace or that was the decoy necklace and left it their for bait for Yeo-Joo. When Kei sends Yeo-Joo to go shopping and Jin volunteers but in the end Kei and Alex go with her? that was kinda weird because Kei and Jin made it seem like she was going to go by herself? What I found really ridiculous was Ji-Soo burning all her hands by lifting up her cup of coffee?? I do not think she could get burns that severe from holding a cup. Another thing that was weird was that Alex made Yeo-Joo investigate Hee-Young and why she was with her boss? How did Alex even know anything about that? and why did he think it was a concern? It only became a problem because the mother investigated Hee-Young and it did not seem to look like Alex even knew that. One thing that was shocking was at the end when Yeo-Joo kissed Alex? WHAT? that was crazy!! and then Kei saw, I mean he has got to be wondering if she is a girl by now!! I mean she has fallen on him a couple of times and you think he would realize?? the way the clothes fit her, she just looks like a girl!! I wished they would have shown more of Kei at the competition!! Anyway this was an alright episode but I found that there were a lot of distracting problems in this episode this time.
