anee, an animator, and Junah, a scriptwriter, are lovers leading a peaceful life together until one day, an old friend of Wanee's comes to visit and reminds Wanee of her first love, her stepbrother. Memories and reality create a romantic triangle that Wanee must resolve. Very realistic relationships between all the characters. The watercolor sequence at the end is the most beautiful animation I have ever seen. A very touching film.
