Mental Coach Jegal

Gil is now living a completely different life as a successful mental coach. His old friend asks him to coach his sister, who is struggling with a slump.

Despite her injury, Ga-eul doesn't give up. Gil takes her to an injured athletes' club in an attempt to make her give up.

Ga-eul goes to the final match despite Gil's objections but ends up eliminated. Gil's final plan brings about an unexpected result.

Coach Oh's assault on players is exposed as Gil intended, but others sign a petition to bring him back-putting Ga-eul in crisis as the whistleblower.

Mu-gyeol is suspected of doping. When the anti-doping committee arrives, Gil stops him from running away. Meanwhile, Ga-eul ends her counseling with Gil due to a misunderstanding.

Ga-eul can't decide between sport event and national team. Mu-gyeol wants to prove himself in the national team trial. What will Gil do for the two, who are being stubborn and refusing counseling?
