Both dramas begin with the FL searching for someone she met years ago who she intends to marry and can only identify by a mark of some kind (birthmark vs. a mark he draws). She identifies the ML as this person and begins following him despite his rejection and having no memory of her. Just as he's falling for her, she begins to believe someone else is the person she's looking for. Both FLs are forward, quirky, offbeat/unusual, and endearing.
