Mood of the Day (2016)

Soo-jung has been with her boyfriend for 10 years, but their romance is now nothing but a lukewarm relationship. The night before her business trip to Busan, Soo-jung heard that her friend is getting married to her first love, and feels distracted. On the train to Busan, she sits next to Jae-hyun, who’s claiming himself as an Agapemonite, an obscure Christian sect where men took many spiritual brides, and that he will willingly jump into bed with a woman for one night. Falling for her gorgeous hips, he keeps coming on to her during the journey. She tries to push him away, but ends up sharing a car ride to Busan with him due to the sudden breakdown of the train. She begins to slowly open up to him as he consistently tries to win her heart. And as the time passes on the road, she gets to see the true inside of Jae-hyun, hidden behind his featheriness and finds herself attracted to him.
