YU and CHUNG are both transferred to the Cardiothoracic Surgery Department to carry on with their practicum, which is a really pleasant surprise for CHUNG. Dr CHIN HO-TAK is so impressed with YU’s calmness and decisiveness during the surgery that he tries to convince her to choose the Cardiothoracic specialty as her long-term career. CHUNG invites YU home to watch an educational movie on Cardiothoracic surgery, but it turns out that… KI asks her colleagues to sign a petition against the punishment imposed on KIN, but KIN does not feel grateful at all and denies having a romantic relationship with KI. KIN and YU have dinner together, during which they spot the people at the next table playing with miniature cars. Through their conversation, they come to realize that the both of them are seriously into miniature vehicles. They suggest having a competition between themselves and they end up having great fun with that. YU runs into ANG in the hospital, during which ANG reveals that she has injured her wrist in a driving lesson but is most reluctant to let KIN know. KIN forbids ANG to take any further driving lessons, and HONG finally plucks up the courage to point out that it is he himself who needs to learn driving. (Source: tubitv)
