This is what I think that happened 3 years ago in the drama according to what I've watched until now. So, since…
Jun Young probably did not fully recover and had to quit badminton. She was sad and left the country, and even broke up with her bf. FL felt guilty and ran away too and many thought she is involved in a bribery case and that is why she disappeared. Jung Hwan and Young Shim is mad at FL bcz JY had to quit and TY left without saying anything. This is just my theory. I guess ML is probably unaware of what really happened as JY said she did not tell the family, they like all must be thinking accident happened bcz she went to train in the mountains. I guess JY is keeping in contact with ML, but do not talk with each other often and that is why he asks her to reply within a week.
No...If you watch episode 6 ..she sends some one to Fountain abode to look into Lanxis background ...which was…
Yeah that's why I am confused, ML asks her right, why she looked in to him, so how did he explain to her how he fond out she wanted Fountain abode t look in to him, did I miss something?
