This one has a "Free Hugs" character and another character who claims the idea is worthy of the Nobel Peace Prize ... just so you know the terrain here. Four couples, two win, two lose. There's death and crying and violins. Standard Korean multi-romance with melodrama and cuteness. Main reason to see: you need to see everything Yeon-hee Lee does. She's fabulous.
Several people experience a miracle of love under the spell of a solar eclipse. Se-jin is obsessively in love with a very bizarre young woman named Ju-won. So-hyun confesses her feeling for Ji-wu by clinging to him and asking him how to become a strong drinker. Jeong-seok is a single father working as a copywriter, loved by Su-jeong, whose advances he rejects every time. Jin-man is a free-hug activist who returns to korea to meet his old flame.
