Overall: my advice is to watch ep 1-3, 7 and 8. This series could have been a 9.5 but the paper thin/cliched plot and too many side characters lowered my rating. 8 episodes about 20 minutes each aired on Viki (U.S), GagaOOLala & WeTV depending on your country.

What I Liked
- the child actors were adorable and did a great job (though I was confused about who was who)
- heart fluttering moments, boss Jun had some excellent flirting/innuendo laced conversations
- really good kissing/intimacy in the last episode
- that gift they received was awesome and how boss Jun had it in his hand at the end (this is a first I think for kbl)
- Mr. Heart actor cameos in ep 5 (did not enjoy the rest of ep 5 though)
- good communication in episode 7 (finally)
- production value (except poor editing with confusing flashbacks tossed in)

Room For Improvement
- paper thin plot, too much business meetings that I cared zero about, not enough time spent on the leads and explaining their motivations/reactions, why did the other interns bring up this HR nightmare but then it's never a problem? cliche poor communication skills (a 1 sentence text would clear up the misunderstanding in ep 5)
- what on earth is boss Jun's "plan?" Why did he wait until now? Why does he act like that with her and not clarify things? How stupid is he? Even his unworldly hotness couldn't save his nonsense actions, the writers never even bothered explaining why the two boys couldn't/didn't keep in touch
- too many characters that were not well developed, why was everyone so in love with intern Jun, he's nice but ????
- confusing flashbacks that weren't immediately apparent were flashbacks and didn't contribute much to the paper thin plot
- translation error in ep 1? confused who is who in the childhood flashbacks
