Synopsis: A romance between a sole heir to a large corporation who has 7 personalities and a 1st year psychiatrist resident who becomes his secret doctor.
Despite the many tragedies in his life, Do Hyun grows up well and is well known in his American university as the guy who is nice to everyone. Do Hyun's friend is both amazed at how good he is at everything he does and frustrated with his willingness to please everyone.
Confused by the memories, Do Hyun snaps back into reality to find the girl he was trying to help has just named him as the bad guy to the police.
A blue light flashes across Do Hyun's eyes and we see him looking in the mirror with a smile. Changed completely from top to bottom, this new Do Hyun goes back to the house he was at earlier that day and proceeds to beat the perpetrator until the guy begs for mercy and agrees to never touch Do Hyun's classmate again.
The next morning, Do Hyun wakes up to find himself not only dressed strangely but also without any recollection of what happened last night.
Despite what Do Hyun decided, his other personality has different ideas, and Do Hyun wakes up one day to find himself on a plane arriving in the Korea International Airport. Via a recording on his phone, one of Do Hyun's other personality - Shin Se Gi informs Do Hyun that he is taking them back to Korea so they could take over Seung Jin group.
Flustered, the first thing Do Hyun does when he sets foot in the airport is to try to book the very next flight back to U.S, but before he could finish his reservation he is greeted by his grandmother's men to escort him back.
Completely confused by the siblings' fight, Do Hyun quickly sneaks off before he gets dragged into another mess.
Turns out, Ri Jin is an author that writes mystery novels under a pseudo name and is quite willing to throw his sister under the bus whenever he needs a fake name to throw reporters off his trail. Oh Ri, a first year psychiatrist resident is very capable at dealing with her patient... especially when it comes to subduing them with her over the shoulder throw. Oh Ri and Ri Jin are twins who might fight but in actuality is really close with one another.
An interesting side note is that Ri Jin has a note book full of newspaper clips of Do Hyun and his family connections.
In the middle of a rather repressed meal, Do Jin's grandmother, Chairman Seo informs him that since he has listed taking over Seung Jin Corp. as one of his conditions for coming back to Korea, then she is going to first prepare him by making him the vice president of an entertainment company.
Do Hyun tries to explain to his grandmother that Se Gi is the one that made the condition and not him, but Chairman Seo just steam rolls over his explanation and tells him to learn from his boss Cha Ki Joon (also his cousin).
Do Hyun gets called to a dance club so he can be introduced to his new co-workers by Ki Joon. Ki Joon also makes a point to specifically introduce a special co-worker - Han Chae Yeon, the girl Do Hyun has been harboring a crush on for years.
Remember back to Ri Jin's words at the airport about leaving the hospital, Do Hyun is quickly convinced that Ri Jin is actually an escaped mental patient. Frustrated at being stopped by Do Hyun while her patient is running away, Ri Jin uses her famous over the shoulder throw on him.
With the wind knocked out of him, Do Hyun starts to grab his head in pain.
Ri Jin laughs at Se Gi's pick up line, and almost doubles over with laughter once again when he adds "You are the first woman to treat me so roughly."
Amidst Se Gi's pick up lines there is one intriguing clue though.
Se Gi "You called me. A long time ago."
Ri Jin tries to deny ever doing such thing, but Se Gi just keep insisting that she did.
After Ri Jin has a good laugh, she is ready to take her leave from the strange man, but Ri Jin looks up to find that a gang of very rough looking men has surrounded them.
Softening at the sight of Se Gi's bleeding head wound, Ri Jin drags Se Gi into the hospital to patch him up. Noticing Ri Jin's Psychiatry department name tag, Se Gi comments "You are a psychiatrist? Ours might be a bad fate." Ha ha!
In an almost desperate tone, Se Gi pulls Ri Jin to her "Remember, the person that has my face but a different name is fake. There is only one Shin Se Gi that has this face. I am the only one, so you have to remember my eyes." Omo, is it weird to starting falling for the hero's split personality? Does this count as cheering for the second lead?
While waiting for Ri Jin to change for their date, Se Gi gets a phone call from Do Hyun's secretary informing Se Gi (who he thought was Do Hyun) that he has found Dr. Park, the psychiatrist that treated Do Hyun in the past. As luck would have it, Dr. Park is Ri Jin's boss which makes Se Gi decide to pay him a quick visit.
Fortunately, Do Hyun comes back to his consciousness and Se Gi disappears thus rescuing Dr. Park from Se Gi's choking hands. It is interesting to note that when Se Gi's personality goes dormant the red tattoo like mark on the back of Do Hyun's neck also disappears. So interesting... is the show trying to tell us the split personalities are actually a real physical thing and not just imaginary?
Shaken to know Se Gi almost used his hands to harm Dr. Park, Do Hyun gets even more nervous to hear from Dr. Park that Se Gi seems to be gaining strength since he supposedly found his first love. Fearful that Se Gi's first love might be none other than his own first love Chae Yeon, Do Hyun rushes out of the hospital.
Speechless, Ri Jin couldn't believe the man who was just professing his love to her would treat her like a complete stranger now.
Before Do Hyun and Chae Yeon's discussion can get too cozy, a call from inside Chae Yeon's house reveals that Do Hyun's cousin, Ki Joon is waiting inside.
Hesitantly, Do Hyun refuses Chae Yeon's invitation for a drink together with his cousin and runs off. Back inside, Chae Yeon drinks with Ki Joon who is in a shower robe and from their conversation it's obvious that both of them is well aware of Do Hyun's crush on Chae Yeon.
Sitting in his car, Do Hyun gets more upset by the second of how fearful he needs to be of Se Gi's presence. Looking at himself from his rear view mirror, Do Hyun screams at Se Gi that he better not touch any of his people or he will kill himself to destroy Se Gi.
Notwithstanding Ri Jin's determination to put the whole mess with Se Gi behind her, she can't help it but start wondering about Se Gi and Do Hyun having different eyes during a conversation with her brother about split personalities.
With a growing confidence that he can stop Se Gi from appearing, Do Hyun gives his all to prepare for his meeting with Seung Jin's board of directors.
Without mincing words, Ki Joon points out to Do Hyun that they are now in a fight to see who will be the heir to Seung Jin Group. Do Hyun gets nervous when Ki Joon brings up the fact he saw Se Gi at the dance club, but becomes speechless when Ki Joon asks "were you doing drugs in U.S?"
Do Hyun's idea sort of worked... except someone name Ferry Park showed up instead of Se Gi .
Oooooo... this one looks promising. I was pretty hooked from episode one and the plot seems to be moving fairly fast. The only thing I am not so sure about is the tattoo appearing and the light that gleams in Do Hyun's eyes whenever one of his personalities comes out. I actually wouldn't mind at all if they go the supernatural route and makes the personalities more than just imaginary but I would have a problem if all these physical signs are just for nothing and the personalities are mere imagination.
I have to confess I have one major problem though... I think I am totally falling under Shin Se Gi's spell. I like Do Hyun too but ... I don't know how much I want Do Hyun to cure his illness if that means we will lose Se Gi. It is going to be an interesting problem if our heroine's romantic interest is actually Se Gi and not Do Hyun... but wait, what if Do Hyun is also just a personality as well?
